Equus Severi: a large bronze equestrian statue of Septimius Severus erected in the middle of the Forum Romanum to commemorate an ominous dream that he had had. It was still standing in Herodian's day (Herodian 2.9.6). It may be shown on certain coins of Septimius (B. M. Coins, Rom. Emp. 5.194 no. 208 pl. 32.3). No certain trace of it has ever been found.
