A Syrian idol, mentioned in Ezekiel 8:14, where the women are represented as weeping for it. It is generally supposed that Tammuz was the same deity as the Phoenician Adonis, and perhaps the Egyptian Osiris. The fabled death and restoration of Adonis, supposed to symbolize the departure and return of the sun, were celebrated at the summer solstice first with lamentation, and then with rejoicing and obscene revels.
