Most of the manuscript sources of Trecento music are from late in the fourteenth or early in the 15th century: some time removed from the composition of the works themselves. The earliest substantial manuscript source of Trecento music is the Rossi Codex, which was compiled sometime between 1350 and 1370 and contains music from the earlier portion of the era. However, other small manuscript sources have been found that expand our knowledge of earlier Trecento repertories. These include the Mischiati fragments of Reggio Emilia, which contain several unique cacce. Other early sources contain sacred repertories. Two folios of Oxford Canon. Misc. 112 preserve a motet by Marchetto da Padova. Further motets are found on the fragment at Venice, San Giorgio Maggiore.
