BEFORE the starry threshold of Jove's courtMy mansion is, where those immortal shapesOf bright aerial spirits live inspheredIn regions mild of calm and serene air,Above the smoke and stir of this dim spotWhich men call Earth, and, with low–thoughted care,Confined and pestered in this pinfold here,Strive to keep up a frail and feverish being,Unmindful of the crown that Virtue gives,After this mortal change, to her true servantsAmongst the enthroned gods on sainted seats.Yet some there be that by due steps aspireTo lay their just hands on that golden keyThat opes the palace of eternity.To Such my errand is; and, but for such,I would not soil these pure ambrosial weedsWith the rank vapours of this sin–worn mould.But to my task. Neptune, besides the swayOf every salt flood and each ebbing stream,Took in by lot, 'twixt high and nether Jove,Imperial rule of all the sea–girt islesThat, like to rich and various gems, inlayThe unadorned bosom of the deep;Which he, to grace his tributary gods,By course commits to several government,And gives them leave to wear their sapphire crownsAnd wield their little tridents. But this Isle,The greatest and the best of all the main,He quarters to his blue–haired deities;And all this tract that fronts the falling sunA noble Peer of mickle trust and powerHas in his charge, with tempered awe to guideAn old and haughty nation, proud in arms:Where his fair offspring, nursed in princely lore,Are coming to attend their father's state,And new–intrusted sceptre. But their wayLies through the perplexed paths of this drear wood,The nodding horror of whose shady browsThreats the forlorn and wandering passenger;And here their tender age might suffer peril,But that, by quick command from sovran Jove,I was despatched for their defence and guard:And listen why; for I will tell you nowWhat never yet was heard in tale or song,From old or modern bard, in hall or bower.Bacchus, that first from out the purple grapeCrushed the sweet poison of misused wine,After the Tuscan mariners transformed,Coasting the Tyrrhene shore, as the winds listed,On Circe's island fell. (Who knows not Circe,The daughter of the Sun, whose charmed cupWhoever tasted lost his upright shape,And downward fell into a grovelling swine?)This Nymph, that gazed upon his clustering locks,With ivy berries wreathed, and his blithe youth,Had by him, ere he parted thence, a sonMuch like his father, but his mother more,Whom therefore she brought up, and Comus named:Who, ripe and frolic of his full–grown age,Roving the Celtic and Iberian fields,At last betakes him to this ominous wood,And, in thick shelter of black shades imbowered,Excels his mother at her mighty art;Offering to every weary travellerHis orient liquor in a crystal glass,To quench the drouth of Phoebus; which as they taste(For most do taste through fond intemperate thirst),Soon as the potion works, their human count'nance,The express resemblance of the gods, is changedInto some brutish form of wolf or bear,Or ounce or tiger, hog, or bearded goat,All other parts remaining as they were.And they, so perfect is their misery,Not once perceive their foul disfigurement,But boast themselves more comely than before,And all their friends and native home forget,To roll with pleasure in a sensual sty.Therefore, when any favoured of high JoveChances to pass through this adventurous glade,Swift as the sparkle of a glancing starI shoot from heaven, to give him safe convoy,As now I do. But first I must put offThese my sky–robes, spun out of Iris' woof,And take the weeds and likeness of a swainThat to the service of this house belongs,Who, with his soft pipe and smooth–dittied song,Well knows to still the wild winds when they roar,And hush the waving woods; nor of less faithAnd in this office of his mountain watchLikeliest, and nearest to the present aidOf this occasion. But I hear the treadOf hateful steps; I must be viewless now.
