Quadra'tus, L. Ni'nnius
tribune of the plebs B. C. 58, distinguished himself by his opposition to the measures of his colleague P. Clodius against Cicero. After Cicero had withdrawn from the city, he proposed that the senate and the people should put on mourning for the orator, and as early as the first of June he brought forward a notion in the senate for his recall from banishment.
In the course of the same year he dedicated the property of Clodius to Ceres (D. C. 38.14
; Cic. pro Sest.
31, post Red. in Sen. 2, pro Dom.
48). Two years afterwards Quadratus is mentioned along with Favonius, as one of the opponents of the Lex Trebonia, which prolonged the government of the provinces to Caesar, Pompey, and Crassus (D. C. 39.35
The last time that his name occurs is in . B. C. 49, when he was in Cicero's neighbourhood in Campania (Cic. Att. 10.16.4
In many editions of Cicero, as also in the Annales of Pighius, he is erroneously called Mummius.
Glandorp, in his Onomasticon, calls him Numius.
