← the temple after Agrippa · 1533
Agrippa's seven squares of the planets, from Saturn's three by three to the Moon's nine by nine, every row, column and diagonal summing alike, as he printed them in the Three Books of Occult Philosophy. On each the old sigils were made by numbering a name's letters and joining the cells in order; the press traces the planet's intelligence and spirit that way, and a name of yours by Agrippa's Latin numeration. The square it shows first is the planetary hour's. Save it; a lock screen is as good as a ring.
What a kamea is. A square of the first so many numbers in which every row, every column and both diagonals add to the same sum, one square for each planet in the old order, the side one greater each time: Saturn three, Jupiter four, Mars five, the Sun six, Venus seven, Mercury eight, the Moon nine. They are older than Agrippa (the Sun's is in Arabic manuscripts centuries before him, and Saturn's is the Chinese lo shu), but his are the ones the West copied, Dürer's included. Agrippa gives, with each, the numbers of the planet, its metal, and the names of its intelligence and its spirit, whose Hebrew letters add up to the square: the intelligence to a row, the spirit to the whole, which is why Sorath, the spirit of the Sun, counts to 666.
How a sigil is traced. Each letter of the name has a number; find each number's cell and join them in order, a ring where the line starts and a bar where it ends; a number too large for the square is read with its last figure dropped until it fits, so 200 on Saturn's square is 20 is 2. The curves Agrippa's engraver put in are left out here; the straight lines are the same cells. The intelligence is drawn solid and the spirit dashed. A name of yours is traced by Agrippa's own Latin table, in which A is 1, K is 10, T is 100 and Z is 500, and is drawn in the other ink. The press keeps no names: nothing is stored or sent, and the image is made in your browser when you save it.
Heinrich Cornelius Agrippa, De occulta philosophia libri tres, Cologne, 1533, Book II chapters 20 and 22; the English of J. F., 1651, is on the shelf as Three Books of Occult Philosophy, at the Esoteric Archives. Public domain. The squares are checked for their sums when the page loads; the intelligences' numbers are Agrippa's. The press is this site's own, in the temple's line like the sigil press and the Monas. One script.
