Labor Twelve: the Capture of Cerberus

As his final Labor, Heracles was instructed to bring the hellhound Cerberus up from Hades, the kingdom of the dead. The first barrier to the soul's journey beyond the grave was the most famous river of the Underworld, the Styx. Here the newly dead congregated as insubstantial shades, mere wraiths of their former selves, awaiting passage in the ferryboat of Charon the Boatman. Charon wouldn't take anyone across unless they met two conditions. Firstly, they had to pay a bribe in the form of a coin under the corpse's tongue. And secondly, they had to be dead. Heracles met neither condition, a circumstance which aggravated Charon's natural grouchiness.
