montem Augustum are mentioned in the twelfth century (Arm. 324 f.;
HCh 195, 254, 265, 315, 380-381) and the portus Aguste or Austu in the
thirteenth, from which marble was shipped for the construction of the
Cathedral of Orvieto (BC 1897, 295). The ruins were converted into a
fortress by the Colonna family, and its destruction in 167 led to considerable damage to the ruins. The fortifications were, however, repaired
in 1241. The body of Cola di Rienzo was burnt here in 1354.
By the sixteenth century it had become a garden; it then belonged
to the Soderini family. (The important drawings by Baldassare Peruzzi,
already discussed by Lanciani in BC 1882, 152-154, are now given in
facsimile by Bartoli, Disegni degli Uffizi. PI. cxi.-cxv. (cxxxii., clxxxiv. relate to the obelisks only). Cf. also BA 1927-8, 30 sqq.
