d-up energy which might essay to improve on caves and pits
and other rude dwellings. By the Nile, perhaps, man first aimed to
overpass the routine of the barest need, and obey his soul. There he
wrought out beautiful vases of fine marble, and invented square
building.

At any rate, the earliest known structure actually discovered, a
prehistoric tomb found in the sands at Hieraconpolis, is already
right-angled. As Lethaby reminds us, modern people take squareness
very much for granted as being a self-evident form, but the discovery
of the square was a great step in geometry.[4] It opened a new era in
the story of the builders. Early inventions must have seemed like
revelations, as indeed they were; and it is not strange that skilled
craftsmen were looked upon as magicians. If man knows as much as he
does, the discovery of the Square was a great event to the primitive
mystics of the Nile. Very early it became an emblem of truth,
justice, and righteousness, and so it remains to this day though
uncountable ages have passed. Simple, familiar, eloquent, it brings
from afar a sense of the wonder of the dawn, and it still teaches a
lesson which we find it hard to learn. So also the cube, the
compasses, and the keystone, each a great advance for those to whom
architecture was indeed "building touched with emotion," as showing
that its laws are the laws of the Eternal.

Maspero tells us that the temples of Egypt, even from earliest times,
were built in the image of the earth as the builders had imagined
it.[5] For them the earth was a sort of flat slab more long than wide,
and the sky was a ceiling or vault supported by four great pillars.
The pavement, represented the earth; the four angles stood for the
pillars; the ceiling, more often flat, though sometimes curved,
corresponded to the sky. From the pavement grew vegetation, and water
plants emerged from the water; while the ceiling, painted dark blue,
was strewn with stars of five points. Sometimes, the sun and moon were
seen floating on the heavenly ocean escorted by the constellations,
and the months and days. There was a far withdrawn holy place, small
and obscure, approached through a succession of courts and columned
halls, all so arranged on a central axis as to point to the sunrise.
Before the outer gates were obelisks and avenues of statues. Such were
the shrines of the old solar religion, so oriented that on one day in
the year the beams of the rising sun, or of som
