Often the epithet is the result of fusion of the Olympian divinity with an older one: Poseidon Erechtheus, Artemis Orthia, reflect intercultural equations of a divinity with an older one, that is generally considered its pendant; thus most Roman gods and goddesses, especially the Twelve Olympians, had traditional counterparts in Greek, Etruscan, and most other Mediterranean pantheons, such as Jupiter as head of the Olympian Gods with Zeus, but in specific cults, there may be a different equation, based on one specific aspect of the divinity. Thus the Greek word ("thrice grand") was first used as a Greek name for the Egyptian god of science and invention, Thoth, and later as an for the Greek Hermes and, finally, the fully equated Roman Mercurius Mercury (both were messenger of the gods). Among the Greeks, T. H. Price notes the nurturing power of might be invoked in sacrifices and recorded in inscription, without specifically identifying Hera or Demeter.
