THREE:After its temporary adoption by the Academy, Pythagoreanism had ceased to exist as an independent system, but continued to lead a sort of underground life in connexion with the Orphic and Dionysiac mysteries. When or where it reappeared under a philosophical form cannot be certainly determined. Zeller fixes on the beginning of the first century B.C. as the most probable date, and on Alexandria as the most probable scene of its renewed speculative activity.385 Some fifty years later, we find Pythagorean teachers in Rome, and traces of their influence are plainly discernible in the Augustan literature. Under its earliest form, the new system was an attempt to combine mathematical mysticism with principles borrowed from the Stoic and other philosophies; or perhaps it was simply a return to the poetical syncretism of Empedocles. Although composed of fire and air, the soul is declared to be immortal; and lessons of holiness are accompanied by an elaborate code of rules for ceremonial purification. The elder Sextius, from whom Seneca derived much of his ethical enthusiasm, probably belonged to this school. He taught a morality apparently identical with that of Stoicism in every point except the inculcation of abstinence from animal food.386 To this might be added the practice of nightly self-confession��an examination from the moral point of view of how one��s whole day has been spent,��were we certain that the Stoics did not originate it for themselves.387Sandy gave up the race very quickly.
