Athenaeus, a contemporary of Archimedes, the author of an extant work Peri Mechanematon (on warlike engines), addressed to Marcellus (probably the conqueror of Syracuse). He is perhaps the same with Athenaeus of Cyzicus, mentioned by Proclus (in Euclid. p. 19) as a distinguished mathematician. The above-mentioned work is printed in Thevenot's Mathematici Veteres, Paris, 1693. (Fabric. Bibl. Graec. iv. p. 222, &c.)
