Thyraeus

In classical mythographic accounts Thyraeus is presented as one of the fifty sons of the impious King Lycaon, placed within the genealogical frameworks used by ancient writers to explain local toponyms and origins. Ancient Arcadian tradition regarded him as the reputed eponymous founder (oikist) of the city Thyraeum in Arcadia; the same tradition held that Thyrea in Argolis and the Thyrean Gulf were named after him. The sources provide no narrative of deeds, exploits, or a biographical life-history beyond his parentage and eponymous function.

No physical description or iconography of Thyraeus is recorded in the supplied sources. He is described only as an Arcadian prince and member of Lycaon’s large progeny; ancient texts cited for this tradition (geographical and antiquarian authors) do not provide corporeal details.

The available sources do not attribute supernatural powers, magical abilities, or specific behaviors to Thyraeus. His role in the tradition is genealogical and etiological—serving as an eponymous ancestor for place-names—rather than as an active supernatural agent. No myths of actions, miracles, or antagonisms are recorded in the cited material.
