Lewis & Short

condălĭum, ii, n. (access. form more nearly related to the Greek: CONDULUS anulus, Paul. ex Fest. p. 38, 14 Müll.; cf. condylus) [κονδύλιον, κόνδυλος; cf. calix = κύλιξ, etc.], a little ring for slaves, Plaut. Trin. 4, 3, 7; 4, 3, 13.
Also, the title of a comedy not now extant, ascribed by Varr. (L. L. 7, § 77 Müll.) to Plaut., but denied to him by Attius (ap. Gell. 3, 3, 9).
