the 12th/13th centuries. They are known as the Apt Manuscript and the Ivrea Codex. They contain motets and mass movements, all of which are polyphonic. Nine out of fourteen Motets by Philippe de Vitry are recorded in the Ivrea Codex, a compilation of eighty-one compositions dating to 1360. It is purported to have been derived from the repertoire used in the Papal Palace at Avignon, since it is so close and offers a sampling of music from the Ars Nova movement. Jewish history According to documentation, Jews lived in Apt as early as the second half of the 14th century. 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. 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. 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. 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. Ecclesiastical history The council of Apt was held on 14 May 1365 in the cathedral of that city by the archbishops and bishops of the provinces of Arles, Embrun and Aix-en-Provence, in the south of France. Twenty-eight decrees were published and eleven days of indulgence were granted to those who would visit with pious sentiments the church of the Blessed Virgin in the Diocese of Apt on the feast of the Exaltation of the Holy Cross and venerate there certain relics of the Cross. Population Sights The chief object of interest is the church of Sainte-Anne (once the cathedral), the building of which was begun about the year 1056 on the site of a much older edifice, but not completed until the latter half of the 17th century. The town was formerly surrounded by massive ancient walls, but these have now been for the most part replaced by boulevards; many of its streets are narrow and irregular. Many Roman remains have been found in and near the town. A fine bridge, the Pont Julien, spanning the
