A raised platform upon which slaves were exposed for sale, so that the intending purchasers
might more readily examine their points (Tibull. ii. 3, 60; Pers. vi.
). The platform was sometimes made to revolve, as appears from Statius (
Silv. ii. 1 Silv., 72
). When the
platform was used in private sales it was called catasta arcana
). See Servus
