HECATONNE´SI(Ἑκατόννησοι: Musconisi), a group of islands in the bay of Adramyttium, between Lesbos and the mainland. Their name, apparently from ἕκατον, a hundred, seems only in a general was to allude to the great number of islands, which is stated by some to have been twenty, and by others forty. (Diod. Sic. 13.77; Steph. B. s. v.) According to Strabo (13. p. 618), however, the name Hecatonnesi signified the islands of Apollo,from his surname Ἕκατος, the far-darter.
