John of Dumbleton (in Gloucestershire, between Cheltenham and Evesham), who died in 1349, spent most of his life in Oxford. A member of a group of mathematicians who studied kinematics and were the first to develop the 'Mean Speed Theorem' in 1334, he is most famous for having written the present work. At the top of this flyleaf is a title and ownership note: 'The Summa of Master John Dumbleton of Brother John Preston'. A third line added below in smaller less formal script is and ownership note and press-mark of St. Augustine's Abbey, Canterbury, where Preston was abbot by 1416.
