（ὀξίς, ὀξύβαφον, ὀξυβάφιον,
). A small shallow vessel, used originally, as the
name denotes, for holding vinegar or sauces, to dip the food into (Poll.
6.85; Ath. 11.494
b; Suidas, s. v. ὀξὶς
). It was afterwards employed for a variety of
other purposes, e. g. for holding salad (Ath.

of the game of cottabos (Ath. 15.667

Originally a vessel for holding vinegar (acetum,
Isidor. 20.4, 12); then any similar vessel (Quintil. Inst.
8.6.35). It was sometimes made of silver (Dig. 34
). The word is used of the socket of the hip-bone (Plin. Nat. 28.179
); the suckers in the
arms of polypi (id. 9.86); and the cup of a flower (id. 18.245), from
which we get the general idea of a small vessel of bell shape with a
wide mouth. The first cut represents an acetabulum, given in Dennis's
vol. i. p. cxii. ; the second,
from Cassini's Pitture antiche,
Rome, 1783 (ap. Daremberg and Saglio, s. v.),
shows two such vessels, probably containing condiments, placed on either
side of a sucking pig

by conjurers in their tricks (Sen. Ep.
45, 7, with
Lipsius's note); and the name was also applied to a kind of cymbal
(Isid. 3.21, 11).
