Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

Ā̆drastēus a, um, or Ādrastīus, a, um, adj., pertaining to Adrastus: Arion, the horse given to Adrastus by Neptune, Stat. S. 1, 1, 52: Adrasteo pallore perfusus, Amm. 14, 11 (with ref. to Verg. A. 6, 480; cf. Adrastus).

Ā̆drastus, i. m., = Ἄδραστος, king of Argos, father-in-law of Tydeus and Polynices, who, acc. to the fable, saw them both die, and turned so pale from grief that he never recovered his former complexion; hence: pallor Adrasti, Verg. 6, 480 Serv.; cf. Ov. P. 1, 3, 79; id. F. 6, 433; Stat. Th. 4, 74 al.
