On the right of the Scala Santa, parallel with the Via Tasso, the
Barracks of the Equites Singulares, or Horse Guards of the Emperors,
of the time of Hadrian, were discovered in March 1886. A noble hall 90
feet long, containing many inscriptions, raised by the discharged
veterans, was discovered; also fragments of statues, and one nearly
perfect of the youthful Bacchus, a work that we may class with the
school of Praxiteles.
