I.Wife of Imbrius
Homer (Iliad 13.173) names Medesicaste only in Imbrius' pedigree: a daughter of Priam born out of wedlock, married at horse-rich Pedaeum. Apollodorus and Pausanias repeat the same Trojan house notice.
A second Medesicaste — daughter of Laomedon and sister of Priam — appears in post-Homeric captive narratives with Aethilla and Astyoche; she is not this atlas node.
II.Homonym care
The atlas id medesicaste-trojan is Priam's illegitimate daughter, wife of imbrius-trojan — not Laomedon's daughter of the same name.
