Note 1615 — BOOK VIII. THE NATURE OF THE TERRESTRIAL ANIMALS.
John Bostock translation
Tacitus and Suetonius mention this separation of the equites from the rest of the spectators: it took place A.U.C. 816.—B. Up to the time of Augustus, A.U.C. 758, the senators, equites, and people sat indiscriminately in the Circus; but that emperor, and after him Claudius, Nero, and Domitian, separated the senators and the equites from the commons.
