PTERO'MA or PTER'ON (πτέρωμα, πτερόν). In architecture, a colonnade on the flank of a temple, or other edifice similarly constructed, projecting from the wall of the cell on each side, like a pair of wings, which resemblance gave rise to the name (Vitruv. iii. 3. 9.); but in buildings which had no side columns, and an outwork on each side of the central pile, similar to what we call wings, or only a blank wall running out like a screen, such an outwork or wall was designated by the same name. Plin. H. N. xxxvi. 4. § 9. Id. xxxvi. 13. Strabo. xvii. 28.
