Mideia (Midea)

In the attested loci where she appears as a nymph, Mideia is recorded as the mother of Aspledon by Poseidon (Pausanias as cited in Theoi; Dictionary of Greek and Roman Biography and Mythology summaries). The name is also applied in classical sources and later reference works to several mortal or semi-mortal women in genealogical lists (for example a woman named Midea among the Danaïdes and other named women in mythographic compilations) and functions as an eponym for towns and heights (Homer's Catalogue of Ships cites a Boeotian Mideia; Pausanias reports a height near Lebadeia called Mideia).

Ancient sources cited in the provided material give no sustained physical description of Mideia. Where she is identified as a nymph (Theoi; Pausanias reference), texts record her role and name but do not provide details of clothing, iconography, or bodily features in the excerpts supplied.

No specific supernatural powers or consistent magical behaviors are recorded in the supplied sources beyond genealogical and eponymic functions. The attested actions are maternal/genealogical (as nymph she is mother of Aspledon by Poseidon) and participation in mythic genealogies (e.g., lists of Danaïdes or other named women). The sources do not attribute particular powers, regional control, or rituals to Mideia in the provided excerpts.
