Cerberus
The guardian at the gates of Hades
The many-headed hound of the Greek underworld, captured without weapons by Heracles for the last of his twelve labours.
Quick answer
In Apollodorus, Cerberus is the guard dog of Hades: a creature with three dog heads, a dragon for a tail, and snakes along his back. Heracles subdues him with his bare hands, shows him to Eurystheus, and returns him to the underworld.

What the source book says
Eurystheus orders Heracles to bring Cerberus up from Hades as his twelfth labour. Heracles enters the underworld at Taenarum, passes its shades and prisoners, and finds the creature at the gates of Acheron. Pluto permits the capture only if Heracles masters Cerberus without using his weapons.[1]
Protected by his cuirass and lion skin, Heracles grips the creature’s heads. The dragon in Cerberus’s tail bites him, but he keeps hold until the hound yields. Heracles carries Cerberus out through Troezen, presents him to Eurystheus, and afterward takes him back to Hades.[1]
Description and abilities
Apollodorus combines three kinds of animal anatomy in a single guardian. The forward heads belong to dogs, the tail is a biting dragon, and smaller snake heads rise from the back. The episode demonstrates strength and resistance, but it does not say that Cerberus breathes fire or give him a colour, height, or precise size.[1]
- Guards a boundary within the underworld
- Has three dog heads in Apollodorus’s account
- Can attack with the dragon at the end of his tail
- Is subdued alive rather than killed
- Returns to his post after the labour is complete
Source realm: the gates of Acheron
Cerberus is found at a guarded threshold inside Hades, near the gates of Acheron. His place in the story is defined by boundaries: Heracles must first find a lawful descent, receive Pluto’s terms, carry the guardian into the living world, and finally restore him to the dead.
Role in Heracles’s final labour
Victory under strict conditions
Heracles cannot solve the labour with his customary bow, sword, or club. Pluto’s condition makes endurance and bodily strength the centre of the contest.
A guardian, not a roaming monster
Cerberus does not seek victims in the living world. Heracles removes him from an assigned post and returns him once Eurystheus has seen the proof.
A visible crossing between worlds
Bringing Cerberus above ground turns an otherwise hidden underworld journey into something that can be presented to the king who ordered it.
