(Σύαγρος), one of the alleged ante-Homeric poets, is said to have flourished after Orpheus and Musaeus, and to have been the first who sang the Trojan War. (Ael. VH 14.21 ; Eustath. ad Il. vol. i. p. 3.) He is perhaps the same as the Sagaris whom Aristotle mentioned, according to Diogenes Laertius (2.46), as contemporary with Homer. (Fabric. Bibl. Graec. vol. i. pp. 6, 291, 562; Bode, Gesch. d. Hellen. Dichtkust. vol. i. p. 247.)
