[4] Fabricius _de Sexto Empirico Testimonia_.

In estimating the weight of these arguments, we must accept with
Pappenheim the close connection of Pyrrhonism with Alexandria,
and the subsequent influence which it exerted upon the
literature of the East. All historical relations tend to fix the
permanent seat of Pyrrhonism, after its separation from the
Academy, in Alexandria. There is nothing to point to its removal
from Alexandria before the time of Menodotus, who is the teacher
of Herodotus,[1] and for many reasons to be considered the real
teacher of Sextus. It was Menodotus who perfected the Empirical
doctrines, and who brought about an official union between
Scepticism and Empiricism, and who gave Pyrrhonism in great
measure, the _éclat_ that it enjoyed in Alexandria, and who
appears to have been the most powerful influence in the school,
from the time of Aenesidemus to that of Sextus. Furthermore,
Sextus' familiarity with Alexandrian customs bears the imprint
of original knowledge, and he cannot, as Zeller implies, be
accepted as simply quoting. One could hardly agree with
Zeller,[2] that the familiarity shown by Sextus with the customs
of both Alexandria and Rome in the _Hypotyposes_ does not
necessarily show that he ever lived in either of those places,
because a large part of his works are compilations from other
books; but on the contrary, the careful reader of Sextus' works
must find in all of them much evidence of personal knowledge of
Alexandria, Athens and Rome.
