Quadratus (ca 100 BCE – 80 CE)
A in G, CMGen 7.13 (13.1034 K.), records Quadratus’ akopon, of a
baker’s dozen ingredients. The cognomen is recorded from the late Republic – MRR 1.196
(L. Ninnius, tr. pl. 58 BCE), 2.239=3.224, and plausibly restored in LGPN 2.271 – and later,
e.g., T, Ann. 6.7 and PIR2 I-507.
PIR2 Q-4.

De Quaternionibus (180 – 300? CE)
Neo-Pythagorean author who cites P, Almagest 8.4, in arguing that the Pythago-
rean tetraktus rules and orders the kosmos. He cites the seasons, the lunar phases, the
elements, the humors, and the dimensions (including “point”) as instances of cosmological
tetrads, and adds the four astrological centers (Horoscopus, Midheaven, Setting, and Nadir),
and the quarters of the year (two equinoxes and two tropics); cf. T S
(pp. 93–99 H.) and A A (CCAG 1 [1898] 143, 146; 8.3 [1912] 105). His
astrological contribution is to argue that the planets’ powers shift as they pass the centers,
and that they are more effective when in quadrature than in trine.
CCAG 9.1 (1951) 172–174.

Sex. Quintilii, Condianus and Valerius Maximus, of Alexandria Troas
(ca 140 – ca 182 CE)
Brothers whose lifelong harmony was proverbial: they were consules ordinarii in 151, both
held influential offices under Marcus Aurelius, and were executed under Commodus, their
sumptuous villa outside of Rome confiscated. Authors of a comprehensive agricultural
treatise which was cited by G M and V A, and of
which echoes survive in the Hippiatrika (Hipp. Berol. 1.18) and the G. The calendar
attributed to them (Geo ̄pon. 3.1) is independently known (Boll).
