Eurythemis

Multiple distinct women named Eurythemis appear in Greek mythographic traditions. In the genealogical account preserved by mythographers (summarized from Apollodorus), Eurythemis, daughter of Cleoboea, is wife of King Thestius of Pleuron and mother of children including Althaea and Leda, linking her to the houses of Calydon and Sparta. John Tzetzes preserves a variant in which a Eurythemis is daughter of Acastus and consort of Actor, mother of Ancaeus. A further tradition names an Eurythemis daughter of Timandreus, sister of Cotto, who with her sister was honored by the Heracleidae. These attestations are genealogical nodes rather than narrative origin myths; they reflect variant local and literary traditions rather than a single authoritative life story.

Ancient sources provide no physical description of Eurythemis. She is known only by name within genealogical lists and literary summaries; surviving materials do not record attributes of dress, form, or visage for her.

No supernatural abilities, powers, or distinctive ritual functions are ascribed to Eurythemis in the cited materials. Her role is social and genealogical: as wife, mother, and daughter she serves to locate better-known figures (for example Leda and Althaea) within familial networks that explain descent and alliance in the heroic age.
