From the sea to Assuan is a little less than 1,100 km. Going inland from
the Mediterranean the traveller first traverses the 'gift of the river', the
prolific Delta. The area (and consequently the name) has the shape of the
fourth letter of
the
Greek alphabet written as
a
capital. It
is
upside down,
an inverted equilateral triangle, its base depending on the sea; its apex is
the point, close to modern Cairo, Roman Babylon, Egyptian Memphis,
from which the river branches into a fan of streams. Southwards from
this spot to Assuan, about 880 km, Egypt consists of the narrow Nile
valley. It is a corridor of green between vari-coloured desert and hills,
nowhere more than 30 km wide, averaging about
11
km, and sometimes,
as at Gebel Silsileh, narrowing to a mere pass between cliffs. At Luxor
and Assuan the valley wears an aspect and climate to delight the senses,
even in the heat of summer. Very different is the asperity of Nubia
further south, inhospitable, infertile, sometimes cold in winter, always
scorching hot in summer. Through its length the river is a first-class
waterway. Above Assuan it
is
a usable route (see below,
p.
139) by which
to penetrate to the heart of the African continent (an additional 4,300 km
to Lake Victoria Nyanza, but hard going from the second cataract, or the
swamps south of modern Khartoum). Use of this waterway turned the
ordinary Egyptian into an excellent sailor, albeit a sailor in inland
waters. In their sacred barques the gods visited each other at festival
time;
when the whole valley was inundated every Egyptian 'messed
about in boats' in order to move from his village to his neighbours'. An
annotated sketch-plan from Zenon's papers outlines the earth-work
needed to protect the temples of a new settlement against flood and river
creatures.

patriotic crocodiles devoured at least a thousand
of Soter's enemies during Perdiccas' mismanaged invasion, and they
even come to the notice of Theocritus.

To its valley floor and its Delta the Nile gave life in abundance.
Greeks commented on the profusion of flowers all the year round, not
merely in spring. Crops of cereals, pulses, vegetables, oil-seeds, dates,
orchard fruit, grapes for the table and the wine-press were of great
richness and variety. Pasturage maintained herds of cattle, sheep and
goats,
the desert offered game, the marshes wild-fowl, duck and
delicious fish such as the salmon-like thrissa that is invoiced for
Alexandrian kitchens in the Zenon papyri. Every year between late June
and November (a miracle to non-Egyptians who expected a river to run
low at that season) the Nile rises in flood and covers the whole valley
floor; fish can be caught far from the main channel. For Egyptians this
was the natural time of holiday and festival, for no work could be done
on the land. After the flood passed its peak, the water could be directed
" P. Mich. Zen. 1.84 (257-25) B.C.).
