Cerberus
In Greek mythology, Cerberus was the three-headed watchdog of Hades. The
only was past him was to throw him a sop which would put him to sleep, as
in Dryden's translation of Virgil's
Aeneid:
No sooner landed, in his den they found
The triple porter of the Stygian sound,
Grim Cerberus, who soon began to rear
His crested snakes, and arm'd his bristling hair.
The prudent Sibyl had before prepar'd
A sop, in honey steep'd, to charm the guard;
Which, mix'd with pow'rful drugs, she cast before
His greedy grinning jaws, just op'd to roar.
With three enormous mouths he gapes; and straight,
With hunger press'd, devours the pleasing bait.
Long draughts of sleep his monstrous limbs enslave;
He reels, and, falling, fills the spacious cave.
