Orphic adj.

"of or related to Orpheus or the doctrines attributed to him," 1670s, from Latinized form of Greek orphikos "pertaining to Orpheus," the legendary master musician of ancient Thrace, son of Eagrus and Calliope, husband of Eurydice, who had the power of charming all living things and inanimate objects with his lyre. His name is of unknown origin. In later times he was accounted a philosopher and adept in secret knowledge, and various mystic doctrines were associated with his name, whence Orphic mysteries, etc. (late 17c.). The earlier adjective was Orphean (1590s). Related: Orphism.
