d of the nineteenth
century there has been another rise in level of about 1 metre.
To the left of the curia was the CHALCIDICUM or Atrium Minervae
(q.v.) (the last remains of which disappeared when the Via Bonella was
made in 1585-90), a courtyard with a colonnade running down each side;
while to the north-west again was the Secretarium Senatus, a hall measur-
ing 18.17 by 8.92 metres, with an apse at the north-east end. An
inscription shows that it had been restored by Junius Flavianus in
311 A.D. and that it was repaired in 412 A.D., after its destruction by
fire, by the then Praefectus Urbi, Epifanius (CIL vi. 1718). The passage
of Cassiodorus, Var. iv. 30, curvae porticus, quae iuxta domum palmatam
(q.v.) posita, forum in modum areae decenter includit, etc., referred by
Jord. i. 2. 257, 258 to the apse of this building, should more probably be
taken to signify the south-western hemicycle of the forum of Trajan
(BC 1887, 64-66; 1889,363; 1899, 88).
