Pillar 7 is the shortest pillar. It also explains the method it uses to encrypt the alphabetic text. It is presumably a pillar to introduce participants to the concepts of encryption.

It contains an unexplained numerical grid near the top of the pillar.

Numerical Grid

At the top of the pillar is a grid of numbers of 5 rows and 26 columns. A triangular glyph surrounds a number (rather than pointing as in other pillars).

Transposition (Caesar) cipher

The remainder of the pillar is filled with a simple cipher - the Caesar cipher.

At the top is a plaintext which makes an obvious reference to Caesar:

A LETTER SHIFT A CIPHER MAKES

A FAMOUS ROMANS NAME IT TAKES

Then below that, it pictorially depicts a letter shift. In this example, A>B, B>C, C>D and so on, with Z>A.

Below this is a cipher text:

This decrypts using a shift of 1 to read

Base

A string of numbers runs around the base.
