Erechtheus

Erechtheus (/ɨˈrɛkθiəs/; Greek: Ἐρεχθεύς) in Greek mythology was the name of an archaic king of Athens, the re-founder of the polis and a double at Athens for Poseidon, as "Poseidon Erechtheus". A mythic Erechtheus and an Erechtheus given a human genealogy and set in a historicizing context—if they ever were really distinguished by Athenians—were harmonized as one in Euripides' lost tragedy Erechtheus, (423/22 BCE) . The name Erichthonius is carried by a son of Erechtheus, but Plutarch conflated the two names in the myth of the begetting of Erechtheus.
