Answer

You can flow the numbers in a magic square of three using Arabic, Hebrew or Chinese numbers (and probably Sanskrit, too). The magic square of three has an interesting history, and not all of it occurs in its country of origin (China), where it has been synonymous with mathematics since the Zhou era.

Knowledge of the Luoshu left China with Muslim scholars and traders. It was known in India from at least 100 CE. From Muslim sources it was transmitted to rabbis and Jewish scholars of Kabbalah, who in turn transmitted knowledge of the Luoshu to Christian Europe.

Frank J. Swetz (in Legacy of the Luoshu) explains why Abenezra (Abraham ben Meir ibn Ezra) is attributed with transmission of the Luoshu to Europe during the Middle Ages. The magic square in the FSUR banner is taken from Abenezra’s book.

During the Middle Ages the Luoshu was used as a talisman against the plague, and even used as a design on dinner plates. In India, and in Muslim lands, it was considered to be helpful during childbirth.
