Most noteworthy perhaps are Deucalion the son of Prometheus, who, along with his wife Pyrrha, survives a great flood sent by Zeus, and Deucalion the soldier, killed by Achilles to avenge Patroclus.
 
Some sources suggest the name is a blending of the elements deukos meaning "sweet, sweet wine" and haliéus meaning "sailor, fisherman", while others suggest it stems from deuo meaning "drenched, wet" — both of which could work in regards to the mythology.
