Talus

Talus was the last Bronze Age man who appeared in the Apollonius of Rhodes’ Arognautica. Talus (Τάλως) lived and defended the island of Crete.

Talus was also a giant, made out of bronze. Instead of blood, Talus had ichor, the life-blood of an immortal. His only weakness was his behind his ankle, where a thin skin covered his vein.

When Jason and the Argonauts tried to land their ship on Crete, as guardian of the island, Talus began hurling huge boulders at the ship. Medea cast a spell upon Talus, causing the giant to drop one boulder on his leg. It landed on his skin behind the ankle, cutting his vein. Talus bled to death.
