These are in fact seven 7x7 tables which form together a larger set of tables. These were given to Dee and Kelley on April 29, 1582 by the Archangels Michael and Uriel. Contained within them are 49 seven letter names of ministers (Kings and Princes) of God.

From this one set of tables, two further tables were made. One simply contains the names of the 49 Ministers. The other lays these names in a circular fashion split into seven sections, with the planetary associations of the Kings.

The cipher for these tables is amazingly simple. Each table has as overall number, that represents the position of the letter within the word i.e. the first letter is in table 1, the second in table 2, etc. Each square of each table contains a letter and a number. The central table, consisting of only B's, is numbered consecutively across the table, and the other six tables are numbered randomly.

To form the names from this table, each letter associated with the same number is read in the table's numeric sequence i.e. The first name is made by taking table 1 number 1, table 2 number 1, table 3 number 1, etc. The names are then written out in order and split into 7 sections of seven names. Each section has a planetary association, and the first name of each section is the King of that section. These names and associations are laid out in this table formed by Dee.
