When and how this happened is not known, but it seems
to have been long after our period. (See also above, ch. 36^.)
Cyrenaica is a massive promontory on the north coast of Africa, lying
between the Greater Syrtis on the west and the Gulf of Bomba to the
east. It is isolated by deserts from the other habitable parts of North
Africa, and closer to the Greek world by sea than to Egypt, being about
300 kilometres from Crete compared with 900 from Naucratis. The land
divides by contour into three clearly distinguished regions: a narrow
coastal plain, an intermediate plateau 200 to 300 metres above sea level,
and the interior plateau (the Jebel) some 300 metres higher still. This
big land-barrier relieves the prevailing north and north-west winds of
their great charge of moisture collected from the sea, and the result-
ing abundant rainfall made for exceptionally favourable agricultural
conditions.

Before the arrival of
the
Greeks the country was inhabited by a mixed
population dominated by the light-skinned Berbers, which was divided
into tribes and ruled by kings. Although some Egyptian influence may
be perceived in their religion (Hdt. iv. 186), there was no political
control. Each tribe occupied
a
defined territory, but since their economy
was chiefly pastoral, there do not seem to have been any large
agglomerations of population.

Chiefly because of Herodotus the history of Cyrene is the best known
of all Greek colonies of the Archaic period. In addition we have separate
information from Pindar (Pyth. iv. 4-8,
59-63;
v. 85-95), much
archaeological evidence,
252
and a document which purports to be the
original foundation decree of the colony.
253
This is preserved in an
inscription, which may be roughly dated to the fourth century B.C., as
an appendix to a Cyrenaean decree of that date. It is a matter of
uncertainty whether, or to what extent, the document faithfully
represents a Theraean public act of the seventh century. Some of the
wording of our text is very unlikely to be that of a seventh-century
decree. However, arguments for taking the whole document and its
contents as a later fabrication can be shown to be unconvincing, so it
is preferable to regard it as a basically authentic record of the
arrangements for despatching the colony.

From these sources we can draw up the following historical recon-
struction. The island of Thera suffered drought and consequent famine.
On the advice of Apollo's oracle at Delphi, they decided to relieve their
