But when the rage of hunger was repress’d, Thus spoke Evander to his royal guest: “These rites, these altars, and this feast, O king, From no vain fears or superstition spring, Or blind devotion, or from blinder chance, Or heady zeal, or brutal ignorance; But, sav’d from danger, with a grateful sense, The labours of a god we recompense. See, from afar, yon rock that mates the sky, About whose feet such heaps of rubbish lie; Such indigested ruin; bleak and bare, How desert now it stands, expos’d in air! ’Twas once a robber’s den, inclos’d around With living stone, and deep beneath the ground. The monster Cacus, more than half a beast, This hold, impervious to the sun, possess’d. The pavement ever foul with human gore; Heads, and their mangled members, hung the door. Vulcan this plague begot; and, like his sire, Black clouds he belch’d, and flakes of livid fire. Time, long expected, eas’d us of our load, And brought the needful presence of a god. Th’ avenging force of Hercules, from Spain, Arriv’d in triumph, from Geryon slain: Thrice liv’d the giant, and thrice liv’d in vain. His prize, the lowing herds, Alcides drove Near Tiber’s bank, to graze the shady grove. Allur’d with hope of plunder, and intent By force to rob, by fraud to circumvent, The brutal Cacus, as by chance they stray’d, Four oxen thence, and four fair kine convey’d; And, lest the printed footsteps might be seen, He dragg’d ’em backwards to his rocky den. The tracks averse a lying notice gave, And led the searcher backward from the cave.
