Secret History of a Rosicrucian

A cryptographic cipher table is arranged in the shape of a cross. The diagram consists of a grid of squares mapping the Latin alphabet, excluding the letter V, to unique geometric symbols and a sequence of numbers from 1 to 24.

• Top vertical arm: Three stacked squares containing the script letter A, a small cross symbol (+), and the number 1.
• Horizontal crossbar (Upper portion): A row of nine script letters (B, C, D, E, F, G, H, I, J) above a row of geometric symbols, primarily right angles and horizontal lines, and a row of numbers (2, 3, 4, 5, 6, 7, 8, 9), with the final cell under the letter J left blank.
• Horizontal crossbar (Lower portion): A row of ten script letters (K, L, M, N, O, P, Q, R, S, T) above a row of geometric symbols, including V-shapes, bracket shapes, and caret shapes, and a row of numbers (10, 11, 12, 13, 14, 15, 16, 17, 18, 19).
• Lower vertical stem: A four-column grid containing the script letters U, W, X, Y, a row of curved bracket symbols, and the numbers 20, 21, 22, 23.
• Bottom vertical tip: Three stacked squares containing the script letter Z, a circle symbol (O), and the number 24.

The cross symbol here likely serves as a null or a special marker in the cipher.

In this row, each letter corresponds to a geometric symbol and a digit. This is a variation of the "Pigpen" or "Masonic" cipher where letters are replaced by fragments of a grid.

Note: The letter V is omitted, as was common in Latin-based alphabets of the time where U and V were interchangeable.
