In the case of this "Magic Square," each row adds to 175, and its total value is 1225. We might note that the same format of the sevenfold square features in "The Kabbala" by Erich Bischoff, as well as in "Hebraeische Amulette mit Magischen Zahlenquadraten" by W. Ahrens, and the mirror image of this square appears in the marginal notes of the previously mentioned 15th century Italian hebrew manuscript:
We should also note that this is not the most popular format of this "Magic Square" in Jewish Magic. That honour belongs to the following square of the seventh order which is extensively addressed in primary Jewish Magical texts, amongst others in "Toldot Adam" by Elijah Baal Shem Tov, "Niflaim Ma’asecha" by Avraham Chamaui, and also in a most interesting Moroccan Practical Kabbalah manuscript in the Jewish Moroccan Heritage Museum in Brussels:
Another interesting variant of this square is again addressed by W. Ahrens in his earlier mentioned book on "Magic Squares," as shown below:
As in the case of the earlier mentioned unusual "Magic Square" of the fifth order addressed in "Hebraeische Amulette mit Magischen Zahlenquadraten," W. Ahrens focussed attention on this variant of the current "Magic Square" for the very same reasons, i.e. the central nine numbers are arranged in the same format as those comprising the "Magic Square" of the third order, as shown below:
As far as the "Magic Squares" of the eighth and ninth order are concerned, I have to date not seen any variants of the "standard" versions. It would seem that beyond the cogitations of Cornelius Agrippa and the "Esh M'tzaref," the marginal notes in the previously referred to 5th Century Italian Hebrew manuscript, the brief references in "The Kabbala" by Erich Bischoff, and the discussion on these "Magic Squares" in "Hebraeische Amulette mit Magischen Zahlenquadraten" by W. Ahrens, there is not much to be found in Jewish Magic on the latter two items.
