Quadratus, a friend and admirer of the younger Pliny, whom he took as his model in oratory. Pliny speaks of him in the highest terms, and praises both his abilities and his excellent moral character.
He was the grandson of the wealthy Ummidia Quadratilla, and inherited two-thirds of her property. [QUADRATILLA.] In the estate thus bequeathed to him was the house formerly inhabited by the celebrated jurist Cassius Longinus.
He married at the age of twenty-four, in the life-time of his grandmother, but lost his wife soon after their marriage. (Plin. Ep. 6.11
.) Two of Pliny's letters are addressed to him (Ep.
6.29, 9.13), in the latter of which Pliny gives an account of the celebrated attack which he made upon Publicius Certus in the senate, in the reign of Nerva, A. D. 96.
