CHALCIDICUM
* an annex to the Curia Iulia built by Augustus (Mon. Anc. iv. I; cf. Mommsen, ad loc.), called τὸ Ἀθήναιον (Cass. Dio li. 22). It seems to have been a sort of porticus-perhaps a repository for records (RE iii. 2039). The Chalcidicum was probably what was afterwards called the Atrium Minervae (Not. Reg. VIII; Jord. i. 2. 255), and in the CURIA of Diocletian (q.v.) it was the central court, through which the via Bonella now runs. See DR 336-338.
