Scholem 1949, p. 244:"It is not to be found at all in medieval synagogues or on medieval ceremonial objects, although it has been found in quite a number of medieval Christian churches again, not as a Christian symbol but only as a decorative motif. The appearance of the symbol in Christian churches long before its appearance in our synagogues should warn the overzealous interpreters. " Scholem, Gershom (September 1949).

Scholem 1949, p. 246:"In the beginning these designs had no special names or terms, and it is only in the Middle Ages that definite names began to be given to some of those most widely used. There is very little doubt that terms like these first became popular among the Muslims, who showed a tremendous interest in all the occult sciences, arranging and ordering them systematically long before the Practical Cabalists thought of doing so.It is not to be wondered at, therefore, that for a long time both the five-pointed and the six-pointed stars were called by one name, the "Seal of Solomon," and that no distinction was made between them. This name is obviously related to the Jewish legend of Solomon's dominion over the spirits, and of his ring with the Ineffable Name engraved on it. These legends expanded and proliferated in a marked fashion during the Middle Ages, among Jews and Muslims alike, but the name, "Seal of Solomon," apparently originated with the Muslims."
