Thyia

In Greek mythology, Thyia (Greek: Θυία Thuia) is a female figure associated with cults of several major gods. The name is derived from the verb "to sacrifice". The name was applied to the white cedar and its genus, Thuja, by Linnaeus (1753).

According to a quotation from Hesiod's lost work the Catalogue of Women, preserved in the De Thematibus of Constantine Porphyrogenitus and in Stephanus of Byzantium's Ethnika, Thyia was the daughter of Deucalion and Pyrrha and mother of Magnes and Makednos (the claimed ancestor of the Macedonians) by Zeus.

In the Delphic tradition, Thyia was also the naiad of a spring on Mount Parnassos in Phocis (central Greece), daughter of the river god Cephissus. Her shrine was the site for the gathering of the Thyiades (women who celebrated in the orgies of the god Dionysos). She was said to have been the first to sacrifice to Dionysus, and to celebrate orgies in his honour. Hence, the Attic women, who every year went to Mount Parnassus to celebrate the Dionysiac orgies with the Delphian Thyiades, received themselves the name of Thyades or Thyiades (synonymous with Maenads).
