quoted by ancient authorities, but was not the one used by Plato, and is therefore some-times thought to have been composed after he wrote; this question cannot at present be decided. An Orphic Theogony given by Aristotle's pupil Eudemus. An Orphic Theogony "according to Hieronymus and Hellanicus". Other versions were: a Theogony put into the mouth of Orpheus by Apollonius Rhodius in his Argonautica an Orphic Theogony quoted by Alexander of Aphrodisias; and a Theogony in Clement of Rome, not specified as Orphic, but belonging to the same school of thought. A long list of Orphic works is given in Suidas (tenth century AD); but most of these are there attributed to other authors. They are: Triagmoi, attributed to the tragic poet Ion, in which there was said to be a chapter called Sacred Vestments, or Cosmic Invocations. The title Triagmoi apparently referred to "the Orphic tripod of three elements, earth, water, fire", referred to by Ausonius and Galen; the latter said that this doctrine was given by Onomacritus in his Orphic poems. The Sacred Discourses, already discussed, usually identified with the Rhapsodiae. Oracles and Rites, attributed to Onomacritus. Aids to Salvation, ascribed to Timocles of Syracuse or Persinus of Miletus; both the work and these writers are otherwise unknown. Mixing-bowls, ascribed to Zopyrus of Heracleia; and The Robe and The Net, also ascribed to Zopyrus, or to Brontinus the Pythagorean. The Net referred to is the net of the body, so called in Orphic literature. To Brontinus was also ascribed a Physica, otherwise unknown. Enthronement of the Mother, and Bacchic Rites, ascribed to Nicias of Elea, of whom nothing else is known. "Enthronement" was part of the rite of initiation practised by the Corybantes, the worshippers of Rhea or Cybele; the person to be initiated was seated on a high chair, and the celebrants danced round him in a ring. The title therefore apparently means "the enthronement-ceremonies as practised by the worshippers of the Great Mother". Connected, perhaps identical with, this was a treatise on Corybantic Rites, quoted by the late Orphic poem Argonautica. A Descent into Hades, ascribed to Herodicus of Perinthus, or to Cercops the Pythagorean, or to the unknown Prodicus of Samos. Other treatises were: an Astronomy or Astrology, otherwise unknown; Sacrificial Rites, doubtless giving rules for bloodless sacrifices; Divination by means of sand, Divination by means of eggs; on Temple-building (otherwise unknown); On the girding
