QUADRIGAE PISONIS
a four-horse chariot erected by order of the senate
in honour of a certain Piso Frugi, who is said to have been one of the
thirty Roman tyrants. It stood within the area afterwards occupied
by the thermae of Diocletian, and was removed when they were
built (vit. trig. tyr. 21;
RE iii. 1390). v. Domaszewski thinks that
the whole story rests on an invention (
SHA 1916, 7. A, 9;
1918, 13. A,
41-46).
