The earliest documentation of Jews in Apt is dated back to the second half of the 13th century, describing the prohibition of meat selling by Jews to Christians.[10] Columbia University Library owns a twelve documents collection of notarial written money lending transactions between Jews and Christians in Apt. One of them describes a transaction between a local Jew called Gartus Bonafossi and a Christian named Iohannes Raymundi.[11] A synagogue was documented as soon as 1416, and around 15 Jewish families were listed by the tax register by 1420. By then, Apt became the fourth largest Jewish community of Provence.[10] The Jewish quarter was situated by the nowadays Place du Postel, and the community itself was mentioned in the writings of the poet Isaac Gorni.
