Erichthonios, who was expressly identified with the Homeric Erechtheus, was by later ages supposed to be buried in the Temple of Polias, i.e. the oldest temple of Athene, on the Acropolis.
Rohde uses Erichthonios as the paradigm case for his thesis that aboriginal chthonic deities are progressively demoted to mortal hero-status and re-housed beneath the temples of the Olympian gods who supersede them.
