Overview
Trophonius (; Ancient Greek: Τροφώνιος Trophōnios) was a Greek hero or daimon or god—it was never certain which one—with a rich mythological tradition and an oracular cult at Lebadaea (Λιβαδειά; Levadia or Livadeia) in Boeotia, Greece.
Etymology and parallel cults
The name is derived from τρέφω trepho, "to nourish". Strabo and several inscriptions refer to him as Zeus Trephonios. Several other chthonic Zeuses are known from the Greek world, including Zeus Μειλίχιος Meilikhios ("honeyed" or "kindly" Zeus), and Zeus Χθόνιος Chthonios ("Zeus beneath-the-earth"), which were other names for Hades.
Similar constructions are also found in the Roman world. For example, a shrine at Lavinium in Lazio was dedicated to Aeneas under the title Iuppiter Indiges (Jupiter in-the-earth).
Family
Trophonius was a son of Erginus, king of Minyan Orchomenus and brother of Agamedes. But Apollo is said to be his actual divine father.
