+  <title>Inferno - Canto I</title>
+</head>
+<body>
+  <h1>Inferno</h1>
+  <h2>Canto I: Dante nella selva oscura</h2>
+  <p>
+    Nel mezzo del cammin di nostra vita<br>
+    mi ritrovai per una selva oscura,<br>
+    ché la diritta via era smarrita.
+  </p>
+  <p>
+    Ahi quanto a dir qual era è cosa dura<br>
+    esta selva selvaggia e aspra e forte<br>
+    che nel pensier rinova la paura!
+  </p>
+  <p>
+    Tant' è amara che poco è più morte;<br>
+    ma per trattar del ben ch'i' vi trovai,<br>
+    dirò de l'altre cose ch'i' v'ho scorte.
+  </p>
+  <p>
+    Io non so ben ridir com' i' v'intrai,<br>
+    tant' era pien di sonno a quel punto<br>
+    che la verace via abbandonai.
+  </p>
+  <p>
+    Ma poi ch'i' fui al piè d'un colle giunto,<br>
+    là dove terminava quella valle<br>
+    che m'avea di paura il cor compunto,
+  </p>
+  <p>
+    guardai in alto e vidi le sue spalle<br>
+    vestite già de' raggi del pianeta<br>
+    che mena dritto altrui per ogne calle.
+  </p>
+  <p>
+    Allor fu la paura un poco queta,<br>
+    che nel lago del cor m'era durata<br>
+    la notte ch'i' passai con tanta pieta.
+  </p>
+  <p>
+    E come quei che con lena affannata,<br>
+    uscito fuor del pelago a la riva,<br>
+    si volge a l'acqua perigliosa e guata,
+  </p>
+  <p>
+    così l'animo mio, ch'ancor fuggiva,<br>
+    si volse a retro a rimirar lo passo<br>
+    che non lasciò già mai persona viva.
+  </p>
+  <p>
+    Poi ch'èi posato un poco il corpo lasso,<br>
+    ripresi via per la piaggia diserta,<br>
+    sì che 'l piè fermo sempre era 'l più basso.
+  </p>
+  <p>
+    Ed ecco, quasi al cominciar de l'erta,<br>
+    una lonza leggiera e presta molto,<br>
+    che di pel macolato era coverta;
+  </p>
+  <p>
+    e non mi si partia dinanzi al volto,<br>
+    anzi 'mpediva tanto il mio cammino,<br>
+    ch'i' fui per ritornar più volte vòlto.
+  </p>
+  <p>
+    Temp' era dal principio del mattino,<br>
+    e 'l sol montava 'n sù con quelle stelle<br>
+    ch'eran con lui quando l'amor divino
+  </p>
+  <p>
+    mosse di prima quelle cose belle;<br>
+    sì ch'a bene sperar m'era cagione<br>
+    di quella fiera a la gaetta pelle
+  </p>
+  <p>
+    l'ora del tempo e la dolce stagione;<br>
+    ma non sì che paura non mi desse<br>
+    la vista che m'apparve d'un leone.
+  </p>
+  <p>
+    Questi parea che contra me venisse<br>
+    con la test' alta e con rabbiosa fame,<br>
+    sì che parea che l'aere ne tremesse.
+  </p>
+  <p>
+    Ed una lupa, che di tutte brame<br>
+    sembiava carca ne la sua magrezza,<br>
+    e molte genti fé già viver grame,
+  </p>
+  <p>
+    questa mi porse tanto di gravezza<br>
+    con la paura ch'uscia di sua vista,<br>
+    ch'io perdei la speranza de l'altezza.
+  </p>
+  <p>
+    E qual è quei che volontieri acquista,<br>
+    e giugne 'l tempo che perder lo face,<br>
+    che 'n tutti suoi pensier piange e s'attrista;
+  </p>
+  <p>
+    tal mi fece la bestia sanza pace,<br>
+    che, venendomi 'ncontro, a poco a poco<br>
+    mi ripigneva là dove 'l sol tace.
+  </p>
+  <p>
+    Mentre ch'i' rovinava in basso loco,<br>
+    dinanzi a li occhi mi si fu offerto<br>
+    chi per lungo silenzio parea fioco.
+  </p>
+  <p>
+    Quando vidi costui nel gran diserto,<br>
+    «<em>Miserere</em> di me», gridai a lui,<br>
+    «qual che tu sii, od ombra od omo certo!».
+  </p>
+  <p>
+    Rispuosemi: «Non omo, omo già fui,<br>
+    e li parenti miei furon lombardi,<br>
+    mantoani per patrïa ambedui.
+  </p>
+  <p>
+    Nacqui <em>sub Iulio</em>, ancor che fosse tardi,<br>
+    e vissi a Roma sotto 'l buono Augusto<br>
+    nel tempo de li dèi falsi e bugiardi.
+  </p>
+  <p>
+    Poeta fui, e cantai di quel giusto<br>
+    figliuol d'Anchise che venne di Troia,<br>
+    poi che 'l superbo Ilïón fu combusto.
+  </p>
+  <p>
+    Ma tu perché ritorni a tanta noia?<br>
+    perché non sali il dilettoso monte<br>
+    ch'è principio e cagion di tutta gioia?».
+  </p>
+  <p>
+    «Or se' tu quel Virgilio e quella fonte<br>
+    che spandi di parlar sì largo fiume?»,<br>
+    rispuos' io lui con vergognosa fronte.
+  </p>
+  <p>
+    «O de li altri poeti onore e lume,<br>
+    vagliami 'l lungo studio e 'l grande amore<br>
+    che m'ha fatto cercar lo tuo volume.
+  </p>
+  <p>
+    Tu se' lo mio maestro e 'l mio autore,<br>
+    tu se' solo colui da cu' io tolsi<br>
+    lo bello stilo che m'ha fatto onore.
+  </p>
+  <p>
+    Vedi la bestia per cu' io mi volsi;<br>
+    aiutami da lei, famoso saggio,<br>
+    ch'ella mi fa tremar le vene e i polsi».
+  </p>
+  <p>
+    «A te convien tenere altro vïaggio»,<br>
+    rispuose, poi che lagrimar mi vide,<br>
+    «se vuo' campar d'esto loco selvaggio;
+  </p>
+  <p>
+    ché questa bestia, per la qual tu gride,<br>
+    non lascia altrui passar per la sua via,<br>
+    ma tanto lo 'mpedisce che l'uccide;
+  </p>
+  <p>
+    e ha natura sì malvagia e ria,<br>
+    che mai non empie la bramosa voglia,<br>
+    e dopo 'l pasto ha più fame che pria.
+  </p>
+  <p>
+    Molti son li animali a cui s'ammoglia,<br>
+    e più saranno ancora, infin che 'l veltro<br>
+    verrà, che la farà morir con doglia.
+  </p>
+  <p>
+    Questi non ciberà terra né peltro,<br>
+    ma sapïenza, amore e virtute,<br>
+    e sua nazion sarà tra feltro e feltro.
+  </p>
+  <p>
+    Di quella umile Italia fia salute<br>
+    per cui morì la vergine Cammilla,<br>
+    Eurialo e Turno e Niso di ferute.
+  </p>
+  <p>
+    Questi la caccerà per ogne villa,<br>
+    fin che l'avrà rimessa ne lo 'nferno,<br>
+    là onde 'nvidia prima dipartilla.
+  </p>
+  <p>
+    Ond' io per lo tuo me' penso e discerno<br>
+    che tu mi segui, e io sarò tua guida,<br>
+    e trarrotti di qui per loco etterno;
+  </p>
+  <p>
+    ove udirai le disperate strida,<br>
+    vedrai li antichi spiriti dolenti,<br>
+    ch'a la seconda morte ciascun grida;
+  </p>
+  <p>
+    e vederai color che son contenti<br>
+    nel foco, perché speran di venire<br>
+    quando che sia a le beate genti.
+  </p>
+  <p>
+    A le quai poi se tu vorrai salire,<br>
+    anima fia a ciò più di me degna:<br>
+    con lei ti lascerò nel mio partire;
+  </p>
+  <p>
+    ché quello imperador che là sù regna,<br>
+    perch' i' fu' ribellante a la sua legge,<br>
+    non vuol che 'n sua città per me si vegna.
+  </p>
+  <p>
+    In tutte parti impera e quivi regge;<br>
+    quivi è la sua città e l'alto seggio:<br>
+    oh felice colui cu' ivi elegge!».
+  </p>
+  <p>
+    E io a lui: «Poeta, io ti richeggio<br>
+    per quello Dio che tu non conoscesti,<br>
+    a ciò ch'io fugga questo male e peggio,
+  </p>
+  <p>
+    che tu mi meni là dov' or dicesti,<br>
+    sì ch'io veggia la porta di san Pietro<br>
+    e color cui tu fai cotanto mesti».
+  </p>
+  <p>
+    Allor si mosse, e io li tenni dietro.

+<title>Moby Dick - Chapter 1. Loomings</title>
+</head>
+<body>
+  <h1>Moby Dick</h1>
+  <h2>Chapter 1. Loomings</h2>
+  <p>
+    Call me Ishmael. <span>Some <span>years</span></span> ago—never mind how
+    long precisely—having little or no money in my purse, and nothing particular
+    to interest me on shore, I thought I would sail about a little and see the
+    watery part of the world. It is a way I have of driving off the spleen and
+    regulating the circulation. Whenever I find myself growing grim about the
+    mouth; whenever it is a damp, drizzly November in my soul; whenever I find
+    myself involuntarily pausing before coffin warehouses, and bringing up the
+    rear of every funeral I meet; and especially whenever my hypos get such an
+    upper hand of me, that it requires a strong moral principle to prevent me
+    from deliberately stepping into the street, and methodically knocking
+    people's hats off—then, I account it high time to get to sea as soon as I
+    can. This is my substitute for pistol and ball. With a philosophical
+    flourish Cato throws himself upon his sword; I quietly take to the ship.
+    There is nothing surprising in this. If they but knew it, almost all men in
+    their degree, some time or other, cherish very nearly the same feelings
+    towards the ocean with me.
+  </p>
+  <p>
+    There now is your insular city of the Manhattoes, belted round by wharves
+    as Indian isles by coral reefs—commerce surrounds it with her surf.
+    Right and left, the streets take you waterward. Its extreme downtown is
+    the battery, where that noble mole is washed by waves, and cooled by
+    breezes, which a few hours previous were out of sight of land. Look at the
+    crowds of water-gazers there.
+  </p>
+  <p>
+    Circumambulate the city of a dreamy Sabbath afternoon. Go from Corlears
+    Hook to Coenties Slip, and from thence, by Whitehall, northward. What do
+    you see?—Posted like silent sentinels all around the town, stand
+    thousands upon thousands of mortal men fixed in ocean reveries. Some
+    leaning against the spiles; some seated upon the pier-heads; some looking
+    over the bulwarks of ships from China; some high aloft in the rigging, as
+    if striving to get a still better seaward peep. But these are all
+    landsmen; of week days pent up in lath and plaster—tied to counters,
+    nailed to benches, clinched to desks. How then is this? Are the green
+    fields gone? What do they here?
+  </p>
+  <p>
+    But look! here come more crowds, pacing straight for the water, and
+    seemingly bound for a dive. Strange! Nothing will content them but the
+    extremest limit of the land; loitering under the shady lee of yonder
+    warehouses will not suffice. No. They must get just as nigh the water as
+    they possibly can without falling in. And there they stand—miles of
+    them—leagues. Inlanders all, they come from lanes and alleys,
+    streets and avenues—north, east, south, and west. Yet here they all
+    unite. Tell me, does the magnetic virtue of the needles of the compasses
+    of all those ships attract them thither?
+  </p>
+  <p>
+    Once more. Say you are in the country; in some high land of lakes. Take
+    almost any path you please, and ten to one it carries you down in a dale,
+    and leaves you there by a pool in the stream. There is magic in it. Let
+    the most absent-minded of men be plunged in his deepest reveries—stand
+    that man on his legs, set his feet a-going, and he will infallibly lead
+    you to water, if water there be in all that region. Should you ever be
+    athirst in the great American desert, try this experiment, if your caravan
+    happen to be supplied with a metaphysical professor. Yes, as every one
+    knows, meditation and water are wedded for ever.
+  </p>
+  <p>
+    But here is an artist. He desires to paint you the dreamiest, shadiest,
+    quietest, most enchanting bit of romantic landscape in all the valley of
+    the Saco. What is the chief element he employs? There stand his trees,
+    each with a hollow trunk, as if a hermit and a crucifix were within; and
+    here sleeps his meadow, and there sleep his cattle; and up from yonder
+    cottage goes a sleepy smoke. Deep into distant woodlands winds a mazy way,
+    reaching to overlapping spurs of mountains bathed in their hill-side blue.
+    But though the picture lies thus tranced, and though this pine-tree shakes
+    down its sighs like leaves upon this shepherd's head, yet all were vain,
+    unless the shepherd's eye were fixed upon the magic stream before him. Go
+    visit the Prairies in June, when for scores on scores of miles you wade
+    knee-deep among Tiger-lilies—what is the one charm wanting?—Water—there
+    is not a drop of water there! Were Niagara but a cataract of sand, would
+    you travel your thousand miles to see it? Why did the poor poet of
+    Tennessee, upon suddenly receiving two handfuls of silver, deliberate
+    whether to buy him a coat, which he sadly needed, or invest his money in a
+    pedestrian trip to Rockaway Beach? Why is almost every robust healthy boy
+    with a robust healthy soul in him, at some time or other crazy to go to
+    sea? Why upon your first voyage as a passenger, did you yourself feel such
+    a mystical vibration, when first told that you and your ship were now out
+    of sight of land? Why did the old Persians hold the sea holy? Why did the
+    Greeks give it a separate deity, and own brother of Jove? Surely all this
+    is not without meaning. And still deeper the meaning of that story of
+    Narcissus, who because he could not grasp the tormenting, mild image he
+    saw in the fountain, plunged into it and was drowned. But that same image,
+    we ourselves see in all rivers and oceans. It is the image of the
+    ungraspable phantom of life; and this is the key to it all.
+  </p>
+  <p>
+    Now, when I say that I am in the habit of going to sea whenever I begin to
+    grow hazy about the eyes, and begin to be over conscious of my lungs, I do
+    not mean to have it inferred that I ever go to sea as a passenger. For to
+    go as a passenger you must needs have a purse, and a purse is but a rag
+    unless you have something in it. Besides, passengers get sea-sick—grow
+    quarrelsome—don't sleep of nights—do not enjoy themselves
+    much, as a general thing;—no, I never go as a passenger; nor, though
+    I am something of a salt, do I ever go to sea as a Commodore, or a
+    Captain, or a Cook. I abandon the glory and distinction of such offices to
+    those who like them. For my part, I abominate all honourable respectable
+    toils, trials, and tribulations of every kind whatsoever. It is quite as
+    much as I can do to take care of myself, without taking care of ships,
+    barques, brigs, schooners, and what not. And as for going as cook,—though
+    I confess there is considerable glory in that, a cook being a sort of
+    officer on ship-board—yet, somehow, I never fancied broiling fowls;—though
+    once broiled, judiciously buttered, and judgmatically salted and peppered,
+    there is no one who will speak more respectfully, not to say
+    reverentially, of a broiled fowl than I will. It is out of the idolatrous
+    dotings of the old Egyptians upon broiled ibis and roasted river horse,
+    that you see the mummies of those creatures in their huge bake-houses the
+    pyramids.
+  </p>
+  <p>
+    No, when I go to sea, I go as a simple sailor, right before the mast,
+    plumb down into the forecastle, aloft there to the royal mast-head. True,
+    they rather order me about some, and make me jump from spar to spar, like
+    a grasshopper in a May meadow. And at first, this sort of thing is
+    unpleasant enough. It touches one's sense of honour, particularly if you
+    come of an old established family in the land, the Van Rensselaers, or
+    Randolphs, or Hardicanutes. And more than all, if just previous to putting
+    your hand into the tar-pot, you have been lording it as a country
+    schoolmaster, making the tallest boys stand in awe of you. The transition
+    is a keen one, I assure you, from a schoolmaster to a sailor, and requires
+    a strong decoction of Seneca and the Stoics to enable you to grin and bear
+    it. But even this wears off in time.
+  </p>
+  <p>
+    What of it, if some old hunks of a sea-captain orders me to get a broom
+    and sweep down the decks? What does that indignity amount to, weighed, I
+    mean, in the scales of the New Testament? Do you think the archangel
+    Gabriel thinks anything the less of me, because I promptly and
+    respectfully obey that old hunks in that particular instance? Who ain't a
+    slave? Tell me that. Well, then, however the old sea-captains may order me
+    about—however they may thump and punch me about, I have the
+    satisfaction of knowing that it is all right; that everybody else is one
+    way or other served in much the same way—either in a physical or
+    metaphysical point of view, that is; and so the universal thump is passed
+    round, and all hands should rub each other's shoulder-blades, and be
+    content.

+  <p>
+    Again, I always go to sea as a sailor, because they make a point of paying
+    me for my trouble, whereas they never pay passengers a single penny that I
+    ever heard of. On the contrary, passengers themselves must pay. And there
+    is all the difference in the world between paying and being paid. The act
+    of paying is perhaps the most uncomfortable infliction that the two
+    orchard thieves entailed upon us. But <i>being paid</i>,—what will compare
+    with it? The urbane activity with which a man receives money is really
+    marvellous, considering that we so earnestly believe money to be the root
+    of all earthly ills, and that on no account can a monied man enter heaven.
+    Ah! how cheerfully we consign ourselves to perdition!
+  </p>
+  <p>
+    Finally, I always go to sea as a sailor, because of the wholesome exercise
+    and pure air of the fore-castle deck. For as in this world, head winds are
+    far more prevalent than winds from astern (that is, if you never violate
+    the Pythagorean maxim), so for the most part the Commodore on the
+    quarter-deck gets his atmosphere at second hand from the sailors on the
+    forecastle. He thinks he breathes it first; but not so. In much the same
+    way do the commonalty lead their leaders in many other things, at the same
+    time that the leaders little suspect it. But wherefore it was that after
+    having repeatedly smelt the sea as a merchant sailor, I should now take it
+    into my head to go on a whaling voyage; this the invisible police officer
+    of the Fates, who has the constant surveillance of me, and secretly dogs
+    me, and influences me in some unaccountable way—he can better answer
+    than any one else. And, doubtless, my going on this whaling voyage, formed
+    part of the grand programme of Providence that was drawn up a long time
+    ago. It came in as a sort of brief interlude and solo between more
+    extensive performances. I take it that this part of the bill must have run
+    something like this:
+  </p>
+  <p>
+    "<i>Grand Contested Election for the Presidency of the United States.</i>
+    "WHALING VOYAGE BY ONE ISHMAEL. "BLOODY BATTLE IN AFFGHANISTAN."
+  </p>
+  <p>
+    Though I cannot tell why it was exactly that those stage managers, the
+    Fates, put me down for this shabby part of a whaling voyage, when others
+    were set down for magnificent parts in high tragedies, and short and easy
+    parts in genteel comedies, and jolly parts in farces—though I cannot
+    tell why this was exactly; yet, now that I recall all the circumstances, I
+    think I can see a little into the springs and motives which being
+    cunningly presented to me under various disguises, induced me to set about
+    performing the part I did, besides cajoling me into the delusion that it
+    was a choice resulting from my own unbiased freewill and discriminating
+    judgment.
+  </p>
+  <p>
+    Chief among these motives was the overwhelming idea of the great whale
+    himself. Such a portentous and mysterious monster roused all my curiosity.
+    Then the wild and distant seas where he rolled his island bulk; the
+    undeliverable, nameless perils of the whale; these, with all the attending
+    marvels of a thousand Patagonian sights and sounds, helped to sway me to
+    my wish. With other men, perhaps, such things would not have been
+    inducements; but as for me, I am tormented with an everlasting itch for
+    things remote. I love to sail forbidden seas, and land on barbarous
+    coasts. Not ignoring what is good, I am quick to perceive a horror, and
+    could still be social with it—would they let me—since it is
+    but well to be on friendly terms with all the inmates of the place one
+    lodges in.
+  </p>
+  <p>
+    By reason of these things, then, the whaling voyage was welcome; the great
+    flood-gates of the wonder-world swung open, and in the wild conceits that
+    swayed me to my purpose, two and two there floated into my inmost soul,
+    endless processions of the whale, and, mid most of them all, one grand
+    hooded phantom, like a snow hill in the air.
