A part of Sextus' books also may have been written in Alexandria. Πρὸς φυσικοὺς could have been written in Alexandria.[1] If these were also lectures, then Sextus taught in Alexandria as well as elsewhere. The history of Eastern literature for the centuries immediately following the time of Sextus, showing as it does in so many instances the influence of Pyrrhonism, and a knowledge of the Hypotyposes, furnishes us with an incontestable proof that the school could not have been for a long time removed from the East, and the absence of such knowledge in Roman literature is also a strong argument against its long continuance in that city. It would seem, however, from all the data at command, that during the years that the Sceptical School was removed from Alexandria, its head quarters were in Rome, and that the Pyrrhonean Hypotyposes were delivered in Rome. Let us briefly consider the arguments in favour of such a hypothesis. Scepticism was not unknown in Rome. Pappenheim quotes the remark of Cicero that Pyrrhonism was long since dead, and the sarcasm of Seneca, Quis est qui tradat praecepta Pyrrhonis? as an argument against the knowledge of Pyrrhonism in Rome. We must remember, however, that in Cicero's time Aenesidemus had not yet separated himself from the Academy; or if we consider the Lucius Tubero to whom Aenesidemus dedicated his works, as the same Lucius Tubero who was the friend of Cicero in his youth, and accordingly fix the date of Aenesidemus about 50 B.C.,[2] even then Aenesidemus' work in Alexandria was too late to have necessarily been known to Cicero, whose remark must have been referred to the old school of Scepticism. Should we grant, however, that the statements of Cicero and Seneca prove that in their time Pyrrhonism was extinct in Rome, they certainly do not show that after their death it could not have again revived, for the Hypotyposes were delivered more than a century after the death of Seneca. There are very few writers in Aenesidemus' own time who showed any influence of his teachings.[3] This influence was felt later, as Pyrrhonism became better known. That Pyrrhonism received some attention in Rome before the time of Sextus is nevertheless demonstrated by the teachings of Favorinus there. Although Favorinus was known as an Academician, the title of his principal work was τοὺς φιλοσοφουμένους αὐτῷ τῶν λόγων, ὧν ἄριστοι οἱ Πυῤῥώνειοι. [4] Suidas calls Favorinus a great author and learned in all science and philosophy,[5] and Favorinus made Rome the centre of his teaching and writing. His date is fixed by Zeller at 80-150 A.D., therefore Pyrrhonism was known in Rome shortly before the time of Sextus.

The whole tone of the Hypotyposes, with the constant references to the Stoics as living present opponents, shows that these lectures must have been delivered in one of the centres of Stoicism. As Alexandria and Athens are out of the question, all testimony points to Rome as having been the seat of the Pyrrhonean School, for at least a part of the time that Sextus was at its head. We would then accept the teacher of Sextus, in whose place he says he taught, as the Herodotus so often referred to by Galen[1] who lived in Rome. Sextus' frequent references to Asclepiades, whom he mentions ten different times by name in his works,[2] speak in favour of Rome in the matter under discussion, as Asclepiades made that city one of the centres of medical culture. On the other hand, the fact that there is no trace of the Hypotyposes in later Roman literature, with the one exception of the works of Hippolytus, as opposed to the wide-spread knowledge of them shown in the East for centuries, is incontestable historical proof that the Sceptical School could not long have had its seat at Rome. From the two passages given above from Sextus' work against physics, he must either have written that book in Alexandria, it would seem, or have quoted those passages from some other work. May we not then conclude, that Sextus was at the head of the school in Rome for a short time, where it may have been removed temporarily, on account of the difficulty with the Empiricists, implied in Hyp. I. 236-241, or in order to be better able to attack the Stoics, but that he also taught in Alexandria, where the real home of the school was certainly found? There it probably came to an end about fifty years after the time of Sextus, and from that centre the Sceptical works of Sextus had their wide-spread influence in the East.

The books of Sextus Empiricus furnish us with the best and fullest presentation of ancient Scepticism which has been preserved to modern times, and give Sextus the position of one of the greatest men of the Sceptical School. His works which are still extant are the Pyrrhonean Hypotyposes in three volumes, and the two works comprising eleven books which have been united in later times under the title of πρὸς μαθηματικούς, one of which is directed against the sciences in general, and the other against the dogmatic philosophers. The six books composing the first of these are written respectively against grammarians, rhetoricians, geometricians, arithmeticians, astronomers and musicians. The five books of the latter consist of two against the logicians, two against physics, and one against systems of morals. If the last short work of the first book directed against the arithmeticians is combined with the one preceding against the geometricians, as it well could be, the two works together would be divided into ten different parts; there is evidence to show that in ancient times such a division was made.[1] There were two other works of Sextus which are now lost, the medical work before referred to, and a book entitled περὶ ψυχῆς. The character of the extant works of Sextus is similar, as they are all directed either against science or against the dogmatics, and they all present the negative side of Pyrrhonism. The vast array of arguments comprising the subject-matter, often repeated in the same and different forms, are evidently taken largely from the Sceptical works which Sextus had resource to, and are, in fact, a summing up of all the wisdom of the Sceptical School. The style of these books is fluent, and the Greek reminds one of Plutarch and Thucydides, and although Sextus does not claim originality, but presents in all cases the arguments of the Sceptic, yet the illustrations and the form in which the arguments are presented, often bear the marks of his own thought, and are characterized here and there by a wealth of humor that has not been sufficiently noticed in the critical works on Sextus. Of all the authors who have reviewed Sextus, Brochard is the only one who seems to have understood and appreciated his humorous side.
