3. A Greek grammarian, of uncertain date. Athenaeus (xi. p. 501) quotes from the fourth book of a work by him, περὶ τοῦ Ἐρατοσθένους Ἑρμοῦ. He also wrote upon Homer (Schol. ad Il. φ. 122), and on Euripides (Schol. ad Eurip. Med. l). If the reading in Harpocration (s. v. Ἀργᾶς), is correct, Timarchus was a native of Rhodes, and was a writer on glosses. But as we find elsewhere mention of a Rhodian named Timachidas, who was a glossographer, some critics propose to alter the reading in Harpocration. The reason is not a very convincing one.
