it is thought that the Artist Pamela Colman Smith, was influenced in part by the Sola Busca Deck of the late 15th Century. The photographs of the deck were at the British Museum, if memory serves me. Now both the Knight and the Page were shown on a barren landscape in much the same poses.
On both the tunics is a design of salamanders, whom symbolises the element of fire. In Christian thought a salamander is thought to be sexless- so shows Chastity; also enduring faith and the righteous man. Waite saw the Page as an envoy or messenger and the Knight as departure and flight. The pyramids are in the desert (a fiery place), they have a message for mankind, and they are seen as the departure place for journeys to the otherworld. The Golden dawn called the Page 'the Rose of the Palace of Fire' and the Knight the 'Prince of the Chariot of Fire' The three of the pyramids probably meant child of the royal household for the Page, and the three for the Knight as the third in the relationship of Queen, King and Knight. This is evoked by the or bought to mind by the Pyramids. Then again they might not be pyramids at all. ~Rosanne
