Etymology: Andromakhe: Named for Áνδρομάχη, Andromakhe (‘battle of men’), a character in Greek mythology, she is the wife of Hector, Prince of Troy, and, in Homer’s epic poem Iliad, the mother of Ἀστυάναξ, Astyanax (‘city protector’); paris: Named after Paris, uncle of Astyanax, who fought in the Trojan war (Ref. 46822).
Eponymy: Andromakhe (or Andromache) is a character in Greek mythology: the wife of Hector, Prince of Troy, and the mother of Astyanax. The name was chosen when the authors placed several species formerly in the genus Astyanax into this new genus. Paris is a mythological character in the story of the Trojan War. He was a son of King Priam of Troy who ran off with Helen, wife of Greek king Menelaus (see Homer’s Iliad for the full story). Astyanax, son of Hector, was his nephew. (Ref. 128868), visit book page.
