Quadratilla, Ummidia
a wealthy Roman lady, who died in the reign of Trajan within a little of eighty years of age, leaving two-thirds (ex besse) of her fortune to her grandson and the other third to her granddaughter (Plin. Ep. 7.24). Her grandson was an intimate friend of Pliny. [QUADRATUS, No. 2.] Quadratilla was probably a sister of Ummidius Quadratus, the governor of Syria, who died in A. D. 60, and appears to be the same as the Quadratilla mentioned in the following inscription, discovered at Casinum in Campania: -- Ummidis C. F. Quadratilla amphitheatrum et temnplun Casinatibus sua pecunia fccit. (Orelli, Inscr. No. 781.) It seems that the Ummidii came originally from Casinum. [UMMIDIA GENS.]
