ATTHEON. Acteon, son of Aristaeus and Autonoë, was a skilled huntsman. One day he accidentally came upon Diana bathing with her nymphs. In her wrath, the goddess changed him into a stag; as he ran from the lake, his companions and their hounds thought him fair game and pursued him until the hounds tore him to death (Met III.143-252; OM III.273-570).
The story of Attheon is painted on the walls of Diana's oratory, KnT 2065-2068. Attheon endured Diana's anger, KnT 2302-2303. [Diane]
The form appears in Boccaccio's Tes VII.79.5. The name appears medially, KnT 2065, 2303. The doubled consonant indicates an initial unstressed vowel; intrusive h after t was not pronounced.
