1. T.Didius, probably the author of the sumptuaria lex Didia, which was passed eighteen years after the lex Fannia, that is, in B. C. 143 (Macr. 2.13), in which year T. Didius seems to have been tribune of the people. The lex Didia differed from the Fannia in as much as the former was made binding upon all Italy, whereas the latter had no power except in the city of Rome. There is a coin belonging to one T. Didius, which shews on the reverse two male figures, the one dressed, holding a shield in the left and a whip or vine in the right hand. The other figure is naked, but likewise armed, and under these figures we read T. DEIDI. It is usually supposed that this coin refers to our T. Didius, and Pighius (Annal. ii. p. 492) conjectures with some probability, that T. Didius, some years after his tribuneship, about about B. C. 138, was sent as praetor against the revolted slaves in Sicily. If this be correct, the figures on the coin may perhaps have reference to it. (Morell. Thesaur. p. 151; Eckhel, Doctrin. Num. v. p. 201.)
