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 [Greek: tous philosophoumenous auto ton
logon, hon aristoi hoi Purrhoneioi].[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 _Hypo
