戴奥尼索斯(Dionysus)，亦称巴克斯（Bacchus）或利贝尔（Liber）。

希腊罗马宗教中丰产与植物的自然神，特别以酒与狂欢之神着称。等同於罗马的巴古斯。对他的崇拜长期盛行於小亚细亚，後成为希腊最重要的神之一，而这种崇拜同对亚细亚的神的崇拜有密切关系。他是宙斯和塞墨勒的儿子，後来被迈纳德或巴康特抚养长大。酒的发明者，他四处旅行，广泛教导制酒的艺术。在他的追随者当中有丰产的精灵萨堤尔和西勒诺斯、仙女。他确有预言的才能，而在德尔斐，祭司们几乎把他和阿波罗同等对待。他个人的表徵是一个常春藤的花环，图尔苏斯杖（杖端有松果形物）和一种叫康塔罗斯的双柄大酒杯。在早期艺术中，他被描绘成一个蓄须男子，但後来他变成一个有女性味道的青年男子。

Dionysus

Greek god of vegetation and fruitfulness, known especially as the god of wine and ecstasy. His Roman equivalent was Bacchus. His worship was introduced into Greece from Asia Minor, and he became one of the most important of all the Greek gods, while his cult remained associated with that of many Asiatic deities. A son of Zeus and (according to the standard tradition) Semele, he was brought up by the maenads, or bacchantes. The first creator of wine, he traveled widely teaching the winemaking art, with a following of satyrs, sileni (see satyr and silenus), and nymphs. He had the gift of prophecy and was received at Delphi along with Apollo, though his principal oracle was at Thrace. Festivities called Dionysia or (among the Romans) Bacchanalia were held in his honor; in their earlier years they were wild, ecstatic occasions, and they have often been the subject of artistic representation. Dionysus originally appeared as a bearded man, but later more often as a slim youth. His principal attribute was the thyrsus, a wand bound with vine leaves. The dithyramb, a choral hymn in his honor, is often seen as the basis of Western drama.
