The Triangle and the Pyramid

the tetractys, the delta


A number made visible. Count the points and then find what else in the picture comes in threes.


Six works here carry a triangle, and in this material a triangle is almost always a count rather than a shape.

The plate of Pythagoras of Crotona makes the method explicit. Hall writes that “Pythagoras taught that 10, or the unit of the decimal system, was the most perfect of all numbers”, and the figure above the seated man is the tetractys, ten dots arranged as a triangle, so that a number can be looked at. Hall adds a second voice: “Theon of Smyrna declares that the ten dots, or tetractys of Pythagoras, was a symbol of the greatest importance”. Whether or not the attribution holds, the principle it describes is what the plates keep doing.

Waite does the same thing in one clause. Of the angel on the card of 1909 he notes “on his breast the square and triangle of the septenary”, and the arithmetic is the whole gloss: three and four, side by side, making seven. The shapes are there to be added.

The rest of the triangles in the archive are at the tops of things. One stands white above the Tree of the Sephiroth where the roots gather under the crown. One holds the Name above Hall's throne. One sits gold over the spheres of the Divine Comedy with a rose inside it. None of the three is named in Hall's chapters, and all three are recorded here as observed rather than read. A triangle at the apex of a diagram is doing something, and in this archive nobody has yet written down what.

Three of the six are unread. Hall attributes a claim to Theon of Smyrna at second hand and the archive holds the attribution, not the source. Hall is also writing about Pythagorean teaching rather than quoting it, and no text by Pythagoras survives to check him against.

  2. Arthur Edward Waite, The Pictorial Key to the Tarot, : Waite commissioned the 1909 designs and wrote the key to them, so his account is the closest thing the deck has to an author's statement.

Plates that carry the symbol, tagged by eye and not yet decoded: first where it is the central motif, then where it plays a secondary part. Each opens in the viewer; the key and the notes come with the entry.
