The famous manuscript made in the late 1460s or early 1470s for Princess Beatrice of Aragon is nowadays known as the Mellon Chansonnier. Beatrice took this codex with her to Central Europe, where in 1476 she married the Hungarian king Matthias Corvinus. After his death, in 1491, Beatrice married Vladislaus II of Bohemia and Hungary, but this second marriage was declared unlawful by the pope and in 1501 Beatrice returned to Naples. The codex evidently remained somewhere in Central Europe, because in 1609 the musician Matthaeus Roth, from Glatz, donated it to the scholar Johann Georg Triegler, who was active mainly in Moravia and Upper Silesia and in 1614 published his German translation of the medieval treatise De Sphera. Triegler died before 1622 and, besides the Mellon Chansonnier, four sixteenth-century prints from his estate are preserved in libraries in the Czech Republic. It is still not clear what happened to the Mellon Chansonnier after Triegler’s death, but the codex was later owned by the French collector Joseph Vitta (1860–1942). In 1939 it was bought at an auction in London by Paul Mellon, who donated it to the University of Yale.
