STYMPHALIDES. Stymphalis was a virgin whom the tyrant Aristoclides of Orchomenos wooed. When her father was slain, Stymphalis fled to Diana's temple, where she clung to the altar until she was stabbed to death. Jerome tells her story, Epistola adversus Jovinianum (Letter Against Jovinian) I.41 (PL 23: 272).
Dorigen remembers that Stymphalides, desired by the tyrant Aristoclides, took sanctuary in Diane's temple and clung to the altar while being stabbed to death, FranklT 1387-1394. [Aristoclides: Dorigen]
The form is the Greek patronymic meaning "son of Stymphalis" and seems to have been formed by analogy to Aristoclides or "son of Aristocles." It occurs in final rhyming position, FranklT 1388, and its placement may have determined its form. Interesting variants Simphalides and Nymphalides preserve the Greek patronymic ending even when the scribe is unfamiliar with the name.
