 Inferno 1 and Inferno 2 are both introductory canti, although in quite different ways: Inferno 1 is more universal and world-historical in its focus, while Inferno 2 is more attentive to the plight and history — past and future — of one single man. The hero’s journey through Hell does not begin until Inferno 3. So what happens before we get to Inferno 3? What happens in Inferno 1 and Inferno 2?
 Following the first half of Inferno 1, devoted to the agon of being lost, Inferno 1 and Inferno 2 feature long conversations between Dante-protagonist and Vergil/Virgilio. In these conversations the poet lays out the ideological premises of the journey that the protagonist is about to undertake. Inferno 1 and Inferno 2 do not advance Dante-protagonist’s material journey so much as they provide the underlying ideological foundation on which Dante-poet can build. In other words, canti 1 and 2 lay the ideological foundation without which the pilgrim’s journey would lack credibility.
 The reader will note that in the above paragraphs I use the terms “hero”, “protagonist”, and “pilgrim”, all terms that I chooose in order to distinguish Dante as protagonist from Dante the “poet”. I am introducing the reader to the “bifocals” that we wear as readers of the Commedia, the hermeneutic lenses with which we are able to keep track of the distinction between the poet — the narrator of the story — and the protagonist: the character who participates in the story that is being narrated. One way that we can distinguish the two is by noting the tense used by the author.
 The poet writes about himself and his recollections of his journey to the afterlife in the present tense. The present tense in which he writes occurs long after the experience of the vision, placed by Dante in 1300. The same poet writes in various past tenses of his journey through the afterlife in the spring of 1300, a journey of which he is the protagonist. The protagonist or hero or pilgrim is the voyaging-self within the fiction, as described by the writing-self. The protagonist is the traveler whose story comprises the Commedia’s plot; the poet is the maker of the plot.
 Dante himself offers a useful primer to these categories — protagonist of the plot and maker of the plot — in the first verses of the poem, a primer that we can access by tracking verb tenses. The pilgrim’s story takes place in the past, and thus the first verb of the Commedia is in the past absolute (passato remoto in Italian), a past tense that describes a specific past occurrence: “mi ritrovai in una selva oscura” (I found myself in a dark wood ). In the next verse we are introduced to the workhorse of the plot, the imperfect tense. This is the tense of ongoing and continuing action in the past that is the Commedia’s narrative motor: “che la diritta via era smarrita” (for the straight way was [continued to be] lost ). The first terzina in this way introduces the voyaging-self and launches the storyline of his journey.
 The next terzina introduces the poet, the narrator who is telling the story, and therefore we encounter two verbs in the present tense. One (“è”) refers to the experience of writing and the other (“rinova”) refers to the experience of remembering: “Ah quanto a dir qual era è cosa dura” (Ah, it is hard to speak of what it was ) and “che nel pensier rinova la paura” (which even in recall renews my fear ). In verse 4 the imperfect tense of the verb “to be” (“era”) is the descriptor of the protagonist’s experience in the past: “qual era” (what it was). Next to “era” in the same verse is the present tense of the verb “to be” (“è”), which describes the experience of the writer: how difficult it is (“è” in the present) to speak (“dir”) of what that experience was (“era”) in the past! That past experience was so fearsome that the remembrance of it still now “renews my fear”; the verb “rinova” in “rinova la paura” (6) is in the present tense of the writing writer.
 The third terzina continues with the writer and his recollections in the present of his mortally bitter experience, using two present-tense forms of the verb essere (to be) to communicate its ongoing nature: “Tant’è amara che poco è più morte” (It is so bitter, death is hardly more so ). But the ultimate goal of the bitter experience was to find the good, and in order to treat the good that he found on the journey (thus in the past: “per trattar del ben ch’io vi trovai” [But to retell the good I discovered there 8]), the poet “will tell” of the other things that he saw: “dirò dell’altre cose ch’i’ v’ho scorte” (I will tell of the other things that I saw ). In verse 8 we see the return to the past absolute (“trovai”) and in verse 9 the introduction of two new tenses: the future tense of the author and what he will say—“dirò”—and a new past tense for the protagonist, the passato prossimo or near past (“ho scorte”). By the time the poet arrives at the end of terzina 3 he has put in an array of temporal markers and accustomed us to his toggling back and forth between the events of the past and his recollections of them in the present. The past already has three variants, and the present extends to the future.
 The poet’s deployment of verb tenses in the opening verses of Inferno 1 introduces the reader to some fundamental narrative premises of the Commedia. And, indeed, in Inferno 1 and Inferno 2 Dante-poet is creating the premises that enable the subsequent action to occur. He is laying down the premises that enable the reader to suspend credibility and to “believe” in that action. Thus, the poet is already engaged in the Commedia’s great project of creating a virtual reality.
 Another way in which Dante sets about creating his possible world is by indicating the parameters of his universe, which he does by linking the rising sun to the original moment of creation: “’l sol montava ’n su con quelle stelle / ch’eran con lui quando l’amor divino / mosse di prima quelle cose belle” (the sun was rising now in fellowship / with the same stars that had escorted it / when Divine Love first moved those things of beauty [Inf. 1.38-40]). The sun is rising “with the same stars” that were with it when God first created stars and everything else. It was believed that creation occurred in springtime. Therefore, Dante is telling us that the the sun is in Aries — it is springtime. (See the astronomical diagram below by Louis Moffa.)
 The verses that tell us that the season is springtime constitute the Commedia’s first astronomical periphrasis: Dante uses a description of the stars in the heavens to give us information about the time. The conjuring of the moment when “Divine Love first moved those things of beauty” (the “cose belle” are the stars in the heavens) is also effectively the first of the Commedia’s many creation discourses, a first installment in Dante’s meditation (foregrounded in the Paradiso) whereby the One became the Many. The poem’s first creation discourse is thus embedded in Inferno 1’s astronomical periphrasis for springtime.
 We note too that the ground of being is also the ground of aesthetics: God made cose belle — things of beauty. Moreover, this use of belle is the first occurrence of any form of the adjective “beautiful” in the Commedia. There is a cluster of first occurrences of forms of bello in Inferno 1-3: “cose belle” (Inf. 1.40), “lo bello stilo” (Inf. 1.87), “donna . . . bella” (Inf. 2.53), “bel monte” (Inf. 2.120), “i ciel . . . men belli” (Inf. 3.40).
 Inferno 1 features both the beauty of the universe (“cose belle”) and the beauty of Dante’s poetic style (“lo bello stilo”): in other words, the canto features being, that which is, and Dante’s poetry, that which represents being. The two — being and the representation of being — will go self-consciously in tandem throughout the Commedia. A term more familiar to literary critics than “being” is “reality”; thus, it is not surprising that reality and realism are themes that pulse through Dante Studies.
 Inferno consists of 34 canti, Purgatorio of 33 canti, and Paradiso of 33 canti, making Inferno 1 the “extra” unit of text, as befits a canto that offers a prelude to the journey as a whole. Inferno 1 concludes with a schematic outline of the three regions of the afterlife: verses 114-117 describe Hell, verses 118-120 describe Purgatory, and verses 121-129 describe Paradise. Together, this section offers a blueprint of the entire journey, of all 100 canti of the poem. Therefore, when Dante wrote Inferno 1 he knew, at least in schematic terms, that the Commedia would comprise three regions, likely corresponding to three books.

 Ideas of the afterlife have histories, like all ideas. Dante has a place in the history of the imagining of the Christian afterlife, a place that can be traced and debated. Two Dantean signatures in the forging of his afterlife are the mixing of classical with Christian sources and of high with low culture:
Therefore, although Dante reflects the most informed theological thought on hell, he is certainly not constrained by it. Moving from the theological template, he widens the range of cultural resources available to him in two fundamental ways: one, he utilizes pagan sources as well as Christian ones; two, he does not limit his Christian sources to the high culture of theology. Thus, he explicitly borrows from such (high culture) pagan sources as Aristotle’s Nicomachean Ethics, which he credits as a source for the structure of his hell, and Vergil’s underworld in Aeneid 6, various of whose characters and features he appropriates and transforms. But Dante’s hell also demonstrates clear links to the established popular iconography of hell and to popular cultural forms like sermons, visions, and the didactic poetry of vernacular predecessors such as Bonvesin da la Riva and Giacomino da Verona. As Alison Morgan correctly notes in Dante and the Medieval Other World, Dante ‘‘is the first Christian writer to combine the popular material with the theological and philosophical systems of his day’’ (“Medieval Multiculturalism and Dante’s Theology of Hell,” cited in Coordinated Reading, p. 103).
 The mixing of classical with Christian sources is a Dantean trait already established in the poem’s first verse. Here the pilgrim is lost in a dark wood at the midway point of life’s path, which is to say, at thirty-five years old. Very con veniently, Dante was born in 1265 and in 1300, the year that he stipulates for his afterlife journey, he was precisely thirty-five, midway through a lifespan of seventy years (see Psalm 90:10: “Our days may come to seventy years”)
 The poet has combined biblical and classical motifs to create a uniquely hybrid “middling” textuality. “Nel mezzo” marks a middle-point/meeting-point of cultural imbrication: “Nel mezzo del cammin di nostra vita” (Midway upon the journey of our life [Inf. 1.1]) evokes, as critics have long noted, both biblical and classical precedents, both Isaiah 38:10 (“In the middle of my days I must depart”) and Horace’s injunction in Ars Poetica to commence a narrative “in medias res” (in the midst of things [Ars Poetica, 148]). The mid-point thus boasts both classical and biblical pedigrees.
 To the above well-known intertexts for “Nel mezzo”, I will add two Aristotelian texts: the passage in the Physics where we find Aristotle’s discussion of time, and the passage in Nicomachean Ethics where we find his definition of virtue.
 In the Physics, Aristotle describes time as “a kind of middle-point, uniting in itself both a beginning and an end, a beginning of future time and an end of past time” (Physics 8.1.251b18–26). In his philosophical prose treatise, Convivio, written before the Inferno, circa 1304-1307, Dante shows that he is acquainted with Aristotle’s writings on time, citing the Physics as follows: “Lo tempo, secondo che dice Aristotile nel quarto de la Fisica, è ‘numero di movimento, secondo prima e poi’” (Time, according to Aristotle in the fourth book of the Physics, is “number of movement, according to before and after” [Conv. 4.2.6]).
 When Dante begins the Commedia “Nel mezzo”, it is hard not to think of Aristotle’s definition of time as “a kind of middle-point” and to feel that the poet is alerting us to our existential being in time, also intrinsic to the opening metaphor of life as a path. As humans, we are ineluctably tethered to “number of motion, according to before and after”—to time.
 Now we turn to the second and more explicit Aristotelian resonance in the first verse of the poem, one built into the choice of the very word “mezzo”. Aristotle wrote on virtue as the mean between two vicious extremes in Nicomachean Ethics, Dante, by the time he came to write Inferno 1, had already meditated at length on the Ethics and on the Aristotelian concept of virtue. Indeed, in his canzone Le dolci rime, written circa 1294, long before the Inferno, Dante translates Aristotle from Latin into Italian, referring to the Aristotelian “mean” in Italian as “mezzo”: “Quest’è, secondo che l’Etica dice, / un abito eligente / lo qual dimora in mezzo solamente” (This is, as the Ethics states, a “habit of choosing which keeps steadily to the mean” [Le dolci rime, 85–87; trans. Foster-Boyde]). He returned to the same canzone roughly ten years later in Book 4 of the Convivio, which he devoted to the canzone Le dolci rime and to a discussion of Aristotle’s ethical system, in which virtue is the mean: the mezzo.
 One of the themes of this commentary is the degree to which the Aristotelian idea of virtue as the mean carries over from the fourth book of the Convivio to permeate the deep structures of Dante’s thought. In other words, although Dante certainly resonates to Augustine and other dualist Christian thinkers on the topic of desire, as we shall discuss shortly, he does not keep his analysis within a binary structure, but opens it to the Aristotelian spectrum. It is important to grasp that Aristotle’s idea of the mezzo belongs within a unified and non-dualistic construction of human behavior.
 Both these Aristotelian understandings—of virtue as the mean and of time as a middle-point—inform the first verse of the Commedia. The word mezzo in the Commedia’s first verse is Aristotelian as well as biblical and Horatian. It resonates both to Aristotle on time, in the metaphysical dimension, and to Aristotle on virtue, in the moral-ethical sphere.

 The metaphor “cammin di nostra vita”/“journey of our life” begins the work of conflating the journey of the poem with the existential and personal journeys through time and space that each of us on this planet experiences every day. As Dante had previously written in the Convivio, human life is a “new and never before traveled path”: “[il] nuovo e mai non fatto cammino di questa vita” (the new and never before traveled path of this life [Convivio 4.12.15]). The Commedia’s work of creating a virtual reality, of encouraging its readers to feel that they are journeying along with Dante, begins with the metaphor of life as a path on which we all walk. The walkers are plural and many, and each has her own path; in this sense the paths are many. But we all walk the cammino di questa vita: in this existential sense the path is one. The experience of life as a journey through time and space is an experience shared by all.
 The opening metaphor of the path, of the voyage by land, will shortly be enriched by the simile of a disastrous voyage by sea. The shipwrecked man who climbs from the watery deep to the shore is the first “Ulyssean” reference of the poem (Inf. 1.22-24). The mythic Greek hero Odysseus, Ulysses in Latin, as Dante encountered him in Vergil’s Aeneid and Cicero’s De Finibus and other Latin texts, is a prime reference point in the Commedia, as well as the featured soul of Inferno 26: Ulysses is the quintessential voyager who comes to perdition, who is lost at sea. As many have noted, Ulysses is Dante-pilgrim’s negative double. However, as my book The Undivine Comedy argues, Dante-poet becomes ever more transgressive and Ulyssean as the Commedia proceeds. From the point of view of the writing poet, Paradiso is the most transgressive — the most Ulyssean — part of the poem. The Ulyssean component of the Commedia is a major theme of The Undivine Comedy and of this Commento, and my usage of the epithet “Ulyssean” will be clarified as we proceed.
 The premise of Dante’s journey is that, like Ulysses, he has lost his way: “ché la diritta via era smarrita” (for the straight way was lost [Inf. 1.3]). Moreover, he is not just passively lost; he has actively abandoned the true way: “la verace via abbandonai” (I abandoned the true path [Inf. 1.12]). However, he spies a way forward. He arrives at a hill whose shoulders are clothed by the rays of the sun, named in periphrasis as the planet that leads men straight by all paths:
Ma poi ch’i’ fui al piè d’un colle giunto, là dove terminava quella valle che m’avea di paura il cor compunto, guardai in alto, e vidi le sue spalle vestite già de’ raggi del pianeta che mena dritto altrui per ogne calle. (Inf. 1.13-18)
But when I’d reached the bottom of a hill— it rose along the boundary of the valley that had harassed my heart with so much fear— I looked on high and saw its shoulders clothed already by the rays of that same planet which serves to lead men straight along all roads.
 After resting, the protagonist sets out to climb the hill, “colle” in verse 13 (later called a mountain, in verse 77), whose heights are “dressed” in divine light. He attempts to climb the hill three times and three times he is repulsed and forced backward and downward, to perdition. The poet here creates a “stuttering” narrative texture of repeated “new beginnings” (see chapter 2 of Undivine Comedy for the concept of new beginnings and for the way they play out in the first canti of Inferno), thus giving narrative life to the bumpy and ever-impeded paths of our existential lives. The three beasts who block the pilgrim’s way grow ever more fearsome: the first is a leopard (lonza), then comes a lion (leone), and finally a she-wolf (lupa). Traditionally the three beasts have been identified with lust (lonza), pride (leone), and avarice (lupa).
 Particularly important for the essential Dantean theme of desire as it will be unfolded throughout the Commedia is the lupa, who will be recalled in Purgatorio 20.10-12 for her “fame sanza fine cupa” (dark hunger without end; these verses are quoted in the long passage from page 110 of The Undivine Comedy cited in paragraph 24 below). The she-wolf goes beyond a narrow definition of avarice and embodies the negative polarity in the spectrum of desire: cupiditas.
 Desire is defined in the Convivio as that which we lack: “ché nullo desidera quello che ha, ma quello che non ha, che è manifesto difetto” (for no one desires what he has, but what he does not have, which is manifest lack [Conv. 3.15.3]). Desire is defective, as I write in The Undivine Comedy:
Desire is defective, while the cessation of desire is happiness, beatitude, in a word perfection. Beatitude as spiritual autonomy — as emancipation from the new — is introduced as early as the Vita Nuova, where Dante learns to place his beatitudine not in Beatrice’s greeting, which can be removed (thus causing him to desire, to exist defectively), but in that which cannot fail him: “quello che non mi puote venire meno” (VN 18.4). Since nothing mortal can satisfy these conditions, we either learn from the failure of one object of desire to cease to desire mortal objects altogether, or we move forward along the path of life toward something else, something new. (The Undivine Comedy, p. 26)
 The description of the lupa connotes desire as lack, for she eats and remains hungry, embodying Augustinian cupidity and lack of peace:
The lupa of Inferno 1 illuminates the negative side of the basic human condition whereby disire è moto spiritale and recalls Augustine’s own reduction of all desire to spiritual motion, either in the form of “charity,” desire that moves toward God, or “cupidity,” desire that remains rooted in the flesh. As cupidity, our dark desire, the lupa is quintessentially without peace, “la bestia sanza pace” (Inf. 1.58). Her restlessness and insatiability denote unceasing spiritual motion, unceasing desire: heavy “with all longings” — “di tutte brame” (49) — her greedy craving is never filled, and after eating she is more hungry than before: “mai non empie la bramosa voglia, / e dopo ’l pasto ha più fame che pria” [Inf. 1.98-99]). Her limitless hunger is both caused by unsatisfied desire and creates the condition for ever less satisfaction, since, in Augustine’s words, “When vices have emptied the soul and led it to a kind of extreme hunger, it leaps into crimes by means of which impediments to the vices may be removed or the vices themselves sustained” (De Doctrina Christiana 3.10.16). When the “antica lupa” is recalled as an emblem of cupidity on purgatory’s terrace of avarice (again indicating the common ground that underlies all the sins of inordinate desire), her “hunger without end” is once more her distinguishing characteristic: “Maladetta sie tu, antica lupa, / che più che tutte l’altre bestie hai preda / per la tua fame sanza fine cupa!” (Cursed be you, ancient wolf, who more than all the other beasts have prey, because of your deep hunger without end! [Purg. 20.10-12]). (The Undivine Comedy, p. 110)
 Desire is lack, but therefore it is also the imperative of forward motion, the “spiritual motion” in which we engage to fill the lack. This is precisely the definition of desire that Dante offers in Purgatorio 18: “disire, / ch’è moto spiritale” (desire, which is spiritual motion [Purg. 18.31–32]). Desire leads us astray, but desire also leads us to the good. How we negotiate our impulse of desire, whether we regulate it with our reason — these are the keys to our destiny. Desire for Dante is not wrong per se, but must always be controlled by reason, as he lets us know forcefully in Inferno 5. (Commento on Inferno 5)
 Dante’s interest in the regulation of desire by reason is part of what leads him to value misura, the moderating force in the Aristotelian ethical scheme. Misura, a concept that Dante will first invoke in Inferno 7, is the behavior that keeps us “dwelling only at the mean” (Le dolci rime, 87).
* * *
 Throughout this reading of Inferno I use Italian “Virgilio” to refer to the character in Dante’s poem. In this way I distinguish the character “Virgilio” (invented by Dante Alighieri) from the historical person, Vergil, the Roman author of the Aeneid who lived from 70 BCE to 19 BCE. (On the reasons for my choice of spelling of “Vergil,” see Dante’s Poets, p. 207, n. 25.)
 The narrative structure of Inferno 1 makes the figure Virgilio a literally pivotal presence in the action of the first canto. Structurally and narratologically, Inferno 1 is a canto that divides into two parts: the part that precedes the arrival of Virgilio, and the part that follows the arrival of Virgilio. The first part of Inferno 1 takes place in an ambiguous surreal topography, one that is dream-like and uncanny, organized around mythic binaries: up/down, straight/crooked, light/dark, true/false, life/death. The actual landscape does not change until the entrance into Hell at the beginning of Inferno 3, but the narrative atmosphere, the poem’s tonality, shifts with the arrival of Virgilio in verse 62. His presence historicizes and grounds the text.
 In the first conversation between the pilgrim and Virgilio, Dante-poet moves his narrative from the mythic and visionary exordium of the poem (a the visionary “sleep” of verse 11) toward that mimetic and historical engagement with “reality” for which the Commedia is renowned.
 Indeed, the suture marks that tie the mythic to the historical are not hidden, but left visible, rendered visible by a detail that is worth noting, although to my knowledge not picked up by the commentary tradition: the lupa is — remarkably, and quite unrealistically — present during the entire opening dialogue between Dante and Virgilio. What was Dante’s goal in writing this scene as he does? Why does he choose to construct the unrealistic overlap between the presence of the daunting lupa, so fearsome that she blocks all passage, all forward motion, and the arrival of the Roman poet?
 With complete lack of verisimilitude, the terrifying beast waits quietly and patiently during many tercets of conversation. The dialogue between Dante and Virgilio begins in verse 65, when Dante-protagonist calls out, beseeching pity of the unknown shade who has just appeared, and yet only in verse 88 does Dante finally ask the Roman poet for help. Twenty-six verses have thus elapsed from the beginning of their conversation until the pilgrim, in verse 88, finally points to the lupa and asks for succor:
Vedi la bestia per cu’ io mi volsi: aiutami da lei, famoso saggio, ch’ella mi fa tremar le vene e i polsi. (Inf. 1.88-90)
You see the beast that made me turn aside; help me, o famous sage, to stand against her, for she has made my blood and pulses shudder.
 Let us reconstruct the dialogue that occurs prior to the above request for assistance. Virgilio begins to speak in verse 67, and his first words embed his character in temporal and geographical specificity (at times resulting in curious anachronisms, like his reference to his family as “Lombard” in verse 68). In the phrase “Nacqui sub Julio” (I was born under Julius [Inf. 1.70]), Virgilio situates himself in the time of Julius Caesar (100–44 BCE), thus locating himself with precision in the flow of human history. He then announces that he was a poet and explains, by circumlocution, that he wrote the Aeneid (73-75). Virgilio at this point focuses on his interlocutor and asks Dante why he is going backwards rather than forwards. Why is he returning to the darkness whence he came?: “Ma tu perché ritorni a tanta noia?” (But why do you return to wretchedness? [Inf. 1.76]). Why isn’t he climbing the “delightful mountain” (a reference to the colle of verse 13) that is “the origin and cause of every joy”: “perché non sali il dilettoso monte / ch’è principio e cagion di tutta gioia?” (77-78).
 Dante-traveler does not answer these questions, although they offer the opportunity to address the presence of the she-wolf. In effect the pilgrim rejects the opportunity to beg for protection from the lupa. Why? Because he experiences overwhelming desire to focus on the identity of the shade whom he has just met.
 Dante replies to the shade of the Roman poet by posing his own amazed question, which amounts to “Are you really Virgilio?”: “Or se’ tu quel Virgilio . . . ?” (And are you then that Vergil . . . ? [Inf. 1.79]). In the slippage between the question posed by Virgilio, which pertains to the canto’s major plot-line of Dante’s failure, fear, and distress, and the protagonist’s digressive reply, which opens a new plot-line regarding Dante’s overpowering love for Vergil and his poetry — a love that in the moment takes precedence even over seeking refuge from the lupa and being able to climb the mountain that leads to salvation — we learn something new about this poet. He adores Vergil’s poetry and classical antiquity. We also see how Dante-poet uses dialogue to generate new plot-lines and thus diegetic complexity. He also uses dialogue to construct character.
 Virgilio now explains figuratively the nature of the lupa and the threat that the beast poses: “e dopo ’l pasto ha più fame che pria” (when she has fed, she’s hungrier than before [Inf. 1.99]). We infer that the negative desire the lupa embodies is cupiditas, an ever-unsatisfied hunger and greed that can never be filled. The lupa is so fierce an impediment that the hill that she blocks cannot be climbed; in the next canto she is called precisely the beast “che del bel monte il corto andar ti tolse” (that barred the shortest way up the fair mountain [Inf. 2.120]). Unable to go directly upward, Dante must take a much longer route to the heights by traversing the three realms of the afterlife. Describing the three realms, Virgilio tells Dante that he will eventually come to a place where he must leave him and where another guide, an unnamed woman, will take his place: “con lei ti lascerò nel mio partire” (With her at my departure I will leave thee [Inf. 1.123]).
 This verse, “con lei ti lascerò nel mio partire” (With her at my departure I will leave thee), is signally important: it provides a benchmark that the reader can use to measure Dante’s ability to conjure real affect in real time. Right now, in Inferno 1, Dante-protagonist (and mirroring him the reader) pays little attention to this announcement of Virgilio’s eventual departure. However, when that departure occurs in Purgatorio 30, much time and textual space later, the protagonist (and in my experience as a teacher, most readers) will be distraught, experiencing Virgilio’s “partire” as a personal abandonment. Between Inferno 1 and Purgatorio 30, therefore, Dante-poet convincingly and incrementally changes Dante-pilgrim from the figure we meet in Inferno 1 — a poetic enthusiast who is thrilled to meet the author of the Aeneid but does not care that Virgilio will ultimately leave him — to the man he is in Purgatorio 30: by then his sorrow at the loss of his father-guide is so great that it temporarily eclipses his joy at the arrival of his original lost beloved, Beatrice.
 Let us return to the lovely interlude in which the pilgrim reacts with amazement to being in the presence of a poet whose work has been of seminal importance to him in his own poetic self-fashioning (Inf. 1.82-87). We readers, too, in mimetic reflection of the pilgrim, should be amazed: the guide chosen for this quintessentially Christian quest is the great author of the Latin epic of the founding of Rome. Through the creation of the character of Virgilio and the storyline that he devises for him, Dante-poet engages his deep feelings about classical antiquity, a major theme of this poem.
 Dante’s feelings about classical culture are authentic and conflictual, not at all ironic. Lack of irony is indeed what the poet dramatizes in the pilgrim’s explosive and emotional and deflecting response to Virgilio’s initial questions about his failure to climb the mountain: “Or se’ tu quel Virgilio . . . ?” (Inf. 1.79). Dante’s adoration of classical culture is real: in historiographic terms, Dante’s veneration of classical culture certainly qualifies as an early form of humanism, as will be discussed in the Commento on Inferno 4. But, if Dante’s veneration of classical culture is real, so too is his concern about the non-Christianity of that culture. It is typical of Dante to present us with a paradoxical and challenging both/and, rather than with a simplistic either/or.
 Thus, Dante has his character Virgilio announce that he lived “in the time of the false and lying gods” (“nel tempo de li dèi falsi e bugiardi” [Inf. 1.72]), but he also makes clear his “great love” for the Roman poet: “O de li altri poeti onore e lume / vagliami ’l lungo studio e ’l grande amore / che m’ha fatto cercar lo tuo volume” (O light and honor of all other poets, / may my long study and the intense love / that made me search your volume serve me now [Inf. 1.82-84]). Both statements reflect genuine belief and genuine feeling: Dante does indeed consider Vergil to have lived in a time of false deities, and at the same time he does truly love and honor Vergil’s poetry. Dante’s love for the poet Vergil, which takes poetic form as the protagonist’s love for the character Virgilio, structures conflict and tension into the Commedia. In retrospect we understand that this conflict and tension are already present in the first canto.
 The Commedia will give us ample opportunity to ponder the novelty and significance of a Christian poet who chooses a Roman poet not only as his poetic model but also as a vehicle of his salvation. In Inferno 1 Dante stakes enormous claims for Virgilio, and hence for classical poetry. This he does through his usage of four key words: poeta, saggio, volume, and autore. In chapter 3 of Dante’s Poets, I trace these four words in the Commedia. The following passage focuses on volume and autore:
As compared to poeta and saggio, terms that describe a trajectory or progression, volume and autore are used in only two contexts: in Inferno for Vergil, and in Paradiso for God. The transition is so immense that it both heightens Vergil, the only poet who is an autore and whose book is a volume, and shrinks him by comparison with that other autore, Who is God, and that other volume, which is God’s book (volume is used variously in the last canticle, but always with relation to texts “written by” God, for instance the book of the future, the book of justice, the universe gathered into one volume). Moreover, when God is termed an author, He is not “’l mio autore” (Inf. 1.85), but the “verace autore” (Par. 26.40). (Dante’s Poets, p. 268)
 While the words volume and autore are used only for Virgilio and God, the word poeta traces a poetic lineage in the Commedia. This genealogy leads to Dante himself, in a crescendo that moves from Vergil to Statius to Dante:
If Statius replaces Vergil in Purgatorio 22 when he appropriates for himself (albeit in modified form) the name poeta, the final displacement is accomplished by Dante, when he becomes the only poeta of the last canticle, announcing in Paradiso 25 that he shall return as poet to Florence to receive the laurel crown. Although that hope was never fulfilled, the impact of the phrase “ritornerò poeta” remains undiminished at a textual level, since it reveals the arc Dante has inscribed into his poem through the restricted use of the word poeta: the poetic mantle passes from the classical poets, essentially Vergil, to a transitional poet, whose Christianity is disjunct from his poetic practice (and hence the verse in Purgatorio 22 with its neat caesura: “Per te poeta fui, per te cristiano” ), to the poet whose Christian faith is a sine qua non of his poetics. (Dante’s Poets, p. 269)
 The poetic genealogy that is inscribed into the Commedia reveals the arc of poetic history moving from Vergil to Statius to Dante. It is this arc that I attempt to capture in the sub-titles of chapter 3 of Dante’s Poets: “Vergil: Poeta fui” (“I was a poet”, citing Inf. 1.73), “Statius: Per te poeta fui” (“Through you I was a poet”, citing Purg. 22.73), and “Dante: ritornerò poeta” (“I shall return as poet”, citing Par. 25.8). This poetic genealogy, which is unfolded incrementally, works both to single out Vergil for special honor and ultimately to displace him.
 The history that pierces the mythic penumbra of the Commedia’s overture is Roman history. The first historic moment of consequence that we encounter in this Christian poem belongs to classical antiquity, which is immediately sutured to contemporary Italy. Contemporary Italy is invoked in the “umile Italia” (106) for which Vergilian heroes and heroines gave their lives in the past, leading forward in an uninterrupted continuum:
Di quella umile Italia fia salute per cui morì la vergine Cammilla, Eurialo e Turno e Niso di ferute. (Inf. 1.106-8)
He will restore humble Italy for which the maid Camilla died of wounds, and Nisus, Turnus, and Euryalus.
 That “Italia” needs to be rescued again is clear in Dante’s apostrophe to contemporary “Italia” in Purgatorio 6. Dante depicts Roman history as crucially informing the present: from Roman history we move directly to that of contemporary “Italia” (106), as from Roman poetry (the Aeneid) we move directly to contemporary Italian poetry, Dante’s own “bello stilo che m’ha fatto onore” (the noble style that has honored me ).
 Myth meets history, and the Commedia has begun.

 Aristotle here is referring to the moment, which he considers indistinguishable from time: ªNow since time cannot exist and is unthinkable apart from the moment, and the moment is a kind of middle-point, uniting as it does in itself both a beginning and an end, a beginning of future time and an end of past time, it follows that there must always be time: for the extremity of the last period of time that we take must be found in some moment, since time contains no point of contact for us except in the moment. Therefore, since the moment is both a beginning and an end, there must always be time on both sides of itº (Physics 8.1.251b18-26; in the translation of R. P. Hardie and R. K. Gaye, in The Basic Works of Aristotle, ed. Richard McKeon [New York: Random House, 1941]).
