Historically speaking, the flag or banner derives from totemistic insignia as found in Egypt and, indeed, in most countries. The Persians carried gilded
eagles with outstretched wings on top of long poles; the Medes, three crowns; the
Parthians, a swordblade; the Greeks and Romans had signa, standards and banners. The important point about all these symbols is not the kind of figure used,
but the fact that it is always placed at the top of a pole or mast. This raised
position is expressive of a kind of imperious exaltation, or the will to ‘heighten’
the spiritual significance of the figure or animal by raising it above the normal
level. From this is derived the general symbolism of the banner as a sign of victory
and self-assertion (22).

This is an abstract idea, the antithesis to the mystic concept of
‘Nothingness’ (which is reality without objects and without forms yet nurturing
the seed of all things). In the Egyptian system of hieroglyphs, the hollow is
defined as ‘that place which is created out of the loss of the substance required for
the building of heaven’, and is thus related to space. On the sarcophagus of Seti I,
there is an image of emptiness consisting of the half-full vessel of Nu (or Nou)
which forms an inverted semicircle completed by a second semicircle located
towards one side of the first (19).

describes Nature as an allegorical figure wearing a diadem set with jewels in
imitation of the stars: twelve stones symbolize the signs of the Zodiac and seven
stand for the Sun, the Moon and the five planets (14). This concept is wholly
astrobiological in character, since it partakes of the tendency to bring the discipline of numbers to bear upon living things, and to infuse the astral, the mineral
and the abstract with the vital forces of plant and animal life.
