These traces invite a discussion on the existence of “Jewish Scotism” among the Jews of Catalonia, and after the expulsion, among their descendants, who probably made their way to Italy. The text is among the latest evidence of the use of Catalan in Hebrew characters on the cusp of the sixteenth century.
