Frederick James Crowest

Simon Tunsted (c. 1310 – 1369) was an English Franciscan friar, theologian, philosopher and musician. The authorship of Quatuor Principalia Musicae, a treatise on music, is generally attributed to him. He originated from Norwich, though his year of birth is unknown. In Norwich, he joined a Greyfriars monastery and became a doctor of theology. He went on to become master of the Minorites at Oxford (in 1351).
