Site of Original Rostra.] It was destroyed by fire when the body of the tribune Clodius was burned, A.U.C. 702. Rebuilt by Faustus, the son of Sylla. Destroyed a second time, to do away with the name of Sylla, on pretence of erecting the Temple of Felicity; rebuilt by Julius Cæsar, A.U.C. 711, completed by the Triumvirs, and consecrated by Augustus, who named it the Curia Julia. Again destroyed by fire under Titus, and rebuilt by Domitian, and called Senatus. It was approached by a flight of steps; for "Tarquin carried old Servius out of the Curia, and threw him down the steps to the bottom" (Livy, i. 48). This was the proper Senate House; and when we read of the senators meeting in other places, there was always some special reason for their so doing. The tradition of the church, S. Adriano, is, that it was erected out of the remains of the Senate House, the bronze doors of which were carried off to the Lateran by Alexander VII., where they still remain. An anonymous writer, quoted by Eckhard, states that in A.D. 283, under Carinus, a fire destroyed the Curia Julia, the Græcostasis, the Basilica Julia, and the Forum of Cæsar, all of which were restored by Diocletian, 290. The Senate House seems to have been again destroyed, and rebuilt by Flavianus, prefect of the city, in 399, under the title of "Secretarium Senatus;" another prefect, Eucharius, restored it in 407. _The Church of S. Martino occupies the site of_ THE GRÆCOSTASIS AND SENACULUM. Varro ("Ling. Lat.," v. 155) says: "The Græcostasis was on the right of the Curia, and projected in front of it; and here the Senate received the foreign ambassadors in audience. The Senaculum lay above the Græcostasis, and towards the Temple of Concord, and the senators deliberated in this building with the magistrates who were not entitled to enter the Senate House." Between S. Martino and S. Adriano the Via Bonella runs out of the Forum on the line of THE ARGILETUM,
