A surname of the mystic Dionysus (Dionusos chthonios), whom Zeus, in the form of a dragon, is said to have begotten by Persephone, previously to her being carried off by Pluto (Callim. Fragm. 171, ed. Bentl.; Etym. Magn. s. v. ; Orph. Hymn. 29 ; Ov. Met. vi. 114 ; Nonnus, Dionys. vi. 264). He was torn to pieces by the Titans, though he defended himself bravely, and assumed various forms; and Athena carried his heart to Zeus. (Tzetz. ad Lycoph. 355 ; Lobeck, Aglaopham. p. 547, &c. SABAZIUS)
