(Νουμήνιος), a medical writer, quoted by Celsus (5.18.35, 21.4, pp. 88, 92) and Aetius (4.1.20, p. 621, in which passage for Numius we should read Numenius). He is, perhaps, the native of Heracleia, who was a pupil of Dieuches, and lived probably in the fourth or third century B. C. (Athen. 1.5.) He wrote a poem on fishing, Ἁγιευτικά, which is frequently quoted by Athenaeus. A person of the same name, who wrote on venomous animals, Θηριακά, is quoted by the Scholiast on Nicander. (Fabric. Bibl. Gr. vol. ii. p. 627, ed. vet.)
