The Augustan age (B. C. 36-A. D. 14), favorable as it was to literature, only contributed to the multiplying of copies of the Greek statues, such as we see in so many instances, some of which are of great excellence, and inestimable as reliable evidence of fine Greek sculpture. These copies were sometimes varied by the sculptor in some immaterial point of detail. Nero (A. D. 54-68) is said to have adorned his Golden House with no less than 500 statues, brought from Delphi. In the Baths of Titus, still in existence (they were built on the ground of the house and gardens of Mæcenas), many valuable statues have been discovered. The Arch of Titus furnishes an excellent example of bas-relief of that time, in it the golden candlestick and other spoils from the temple of Jerusalem are shown. Hadrian (A. D. 117-138) encouraged the reproduction of the Greek statues, with great success as regards execution, for his famous villa at Tivoli, and besides these are the statues of his favorite Antinous, which are the most original works of the time. Hadrian’s imperial and liberal promotion of sculpture, gave an immense impetus to the production of statues of every form. All the towns of Greece which he favored made bronze portrait statues of him, which were placed in the temple of Jupiter Olympius at Athens, and the enclosure round more than half a mile in extent was filled with its many statues. The learned Varro speaks of Arcesilaus as the sculptor of Venus Genetrix, in the forum of Cæsar, and of a beautiful marble group of Cupids playing with a lioness, some leading her, others beating her with their sandals, others offering her wine to drink from horns. Under the Antonines arose the outrageous fashion of representing noble Romans and their wives as deities, and this was carried so far that the men are not unfrequently nude as if heroic. The bas-reliefs on the arch of Septimus Severus at Rome, and that which goes by the name of Constantine—though made chiefly of reliefs belonging to one raised in honor of Trajan—show the poor condition of sculpture at that time. The numerous sarcophagi, some made by Greek sculptors for the Roman market, and others by those working at Rome, are other examples of the feeble style of imitators and workmen actuated by no knowledge or feeling of art. Some of these are still to be seen in the collections at Rome, with mythological subjects, the heads being left unfinished, so that the portraits of the family could be carved when required.
