(Εὐπίθιος), an Athenian grammarian, the author of one epigram in the Greek Anthology (Brunck, Anal. vol. ii. p. 402; Jacobs, Anth. Graec. vol. iii. p. 110), which contains all we know of him, and from the contents of which, as well as from its title in the Vatican MS., τοῦ στίξαντος τὴν καθόλου, we learn that Eupithius had spent much grammatical labour on the punctuation and accentuation of the καθολικὴ προσῳδία, or ἡ καθόλου (sc. τέχνη) of Herodian. Herodian flourished under the emperor Marcus Antoninus. (Jacobs, Anth. Graec. vol. x. pp. 186, 187, vol. xiii. p. 895; Fabric. Bibl. Graec. vol. iv. p. 475.)
