Lewis & Short

aerĭ-pes, pĕdis, adj. [aes].

  1. I. Bronzefooted (poet.): tauri, Ov. H. 12, 93: cerva, Verg. A. 6, 802 (since, acc. to fable, they had feet of bronze; hence we need not, with Charis. p. 249; Diom. p. 437 P., and Pomp. p. 449 Lind., take aeripedes for aëripedes from aër, the air, and pes).
  2. II. Metaph., strong of foot; hence, swift of foot, swiftfooted (as in Gr. χαλκόπους sometimes = ἰσχυρόπους): cervi, Aus. Idyll. 11, 14.
