Justin, xx, 4. “Sed trecenti ex juvenibus cum sodalitii juris sacramento quodam nexi, separatam a ceteris civibus vitam exercerent, quasi cœtum clandestinæ conjurationis haberent, civitatem in se converterunt.”
Compare Diogen. Laërt. viii, 3; Apollonius ap. Jamblich. c. 254; Porphyry, Vit. Pyth. c. 33.
The story of the devoted attachments of the two Pythagoreans Damon and Phintias appears to be very well attested: Aristoxenus heard it from the lips of the younger Dionysius the despot, whose sentence had elicited such manifestation of friendship (Porphyry, Vit. Pyth. c. 59-62, Cicero, De Officiis, iii, 10; and Davis ad Cicero, Tusc. Disp. v, 22).
