15 sides; they have therefore the shape of the diamond, one form of the Yoni. The significance of this is too complex for our simple treatise; it may be studied in Crowley's "Berashith." The size of the whole figure is determined by the size of one square of the Tau. And the size of this square is that of the base of the Altar, which is placed upon Malkuth. It will follow then that, in spite of the apparent freedom of the Magician to do anything he likes, he is really determined absolutely; for as the Altar must have a base proportionate to its height, and as that height must be con- venient for the Magician, the size of the whole will depend upon his own stature. It is easy to draw a moral lesson from these considerations. We will merely indicate this one, that the scope of any man's work depends upon his own original genius. Even the size of the weapons must be determined by necessary proportion. The exceptions to this rule are the Lamp, which hangs from the roof, above the centre of the Circle, above the square of Tiphereth; and the Oil, whose phial is so small that it will suit any altar. On the Circle are inscribed the Names of God; the Circle is of green, and the names are in flaming vermilion, of the same colour as the Tau. Without the Circle are nine pentagrams equidistant,' in the ^ Some magicians prefer seven lamps, for the seven Spirits of God that are before the Throne. Each stands in a heptagram, and in each angle of the heptagram is a
