Note 19 — Chapter I · PROLOGUE

E.g. ingenia, “men of talent,” “geniuses” (Sen., Ad Helv., xix. 5; Tac., Agric., ii.). The post-Augustan sense of custodiae as “persons under guard,” “prisoners,” in Plin., Ep., X. xix., and Suet., Tib., lxi., Ner., xxxi., Sen., Ep., v. 7, shows a complete change round from a previous extension of its meaning found in Cic., viz. “persons serving as guards,” “sentinels.” Cf. inquisitio, “investigators,” Plin., Ep., X. xxx.; matrimonia, “wives,” Tac., Ann., II. xiii.; amicitia, “friends,” II. xxvii.; consilia, “advisers,” IV. xl.; affinitatibus et amicitiis, “kindred and friends,” Agr., 44; lectiones, “works to be read,” Quint., I.O., X. i. 45.
