Note 1, p. 423:
In Crowley's own copy of this work, he has written in the margin opposite the Priestess, 'i.e. a sworn whore'. The expression Virgo Intacta in this context is misleading. It means, in fact, that the woman who performs the function of the Priestess should be dedicated solely to the Great Work, like Artemis to Pan. 'A sworn whore' would therefore be a suitable candidate for the office, not a virgin in the ordinary sense.
[white and black] This fails to say whether one is in white and the other in black, or both wear white and black. This is subject to interpretation. Most, however, seem to assume that the Child bearing the censer and perfume wears white, while the other wears black.
[salt] Water and earth are the negative, passive elements. They will be placed at Yesod, the Moon, represented by the font.
[perfume] Fire and air are the positive, active elements. They will be placed at Tiphareth, the Sun, represented by the small altar.
