Lewis & Short

Călābra Cūria, a Curia at the Capitol, so called from the proclamation [calare] of the calendar dates in this place by the priests (hence the gloss, ἱππών βουλή, for which should be read, ἱερῶν βουλή); cf. Varr. L. L. 5, § 13; 6, § 27 Müll.; Macr. S. 1, 15; Paul. ex Fest. s. v. curia, p. 49 Müll.; and Serv. ad Verg. A. 8, 654.
