vidence of Sextus' writings in regard to his native land. It is
nevertheless evident, from his familiarity with the customs,
language, and laws of Athens, Alexandria and Rome, that he must
have resided at some time in each of these cities.

Of all the problems connected with the historical details of the
life of Sextus, the one that is the most difficult of solution,
and also the most important for our present purpose of making a
critical study of his teaching, is to fix the seat of the
Sceptical School during the time that he was in charge of it.
The _Hypotyposes_ are lectures delivered in public in that
period of his life. Where then were they delivered? We know that
the Sceptical School must have had a long continued existence as
a definite philosophical movement, although some have contended
otherwise. The fact of its existence as an organized direction
of thought, is demonstrated by its formulated teachings, and the
list given by Diogenes Laertius of its principal leaders,[1] and
by references from the writings of Sextus. In the first book of
_Hypotyposes_ he refers to Scepticism as a distinct system of
philosophy, [Greek: kai taen diakrisin taes skepseos apo ton
parakeimenon autae philosophion].[2] He speaks also of the older
Sceptics,[3] and the later Sceptics.[4]

Pyrrho, the founder of the school, taught in Elis, his native
village; but even as early as the time of Timon, his immediate
follower, his teachings were somewhat known in Alexandria, where
Timon for a while resided.[5] The immediate disciples of Timon,
as given by Diogenes, were not men known in Greece or mentioned
in Greek writings. Then we have the well-known testimony of
Aristocles the Peripatetic in regard to Aenesidemus, that he
taught Pyrrhonism in Alexandria[6]--[Greek: echthes kai proaen
en Alexandreia tae kat' Aigypton Ainaesidaemos tis anazopyrein
aerxato ton huthlon touton].
