Another late 14th-century composer, probably active in Rome, Abruzzo, and Teramo, was Antonio Zachara da Teramo. While a chronology of his music is yet to be established, it seems that his earlier music, surviving in the Squarcialupi Codex, is related to the style of Landini and Jacopo da Bologna; his later music borrows from the style of the Avignon-centered "Ars subtilior", and indeed, he seems to have supported the antipopes during the split of the papacy after the end of the century, going to Bologna around 1408.
