Professor Middleton printed in his “Illuminated Manuscripts” (pp. 220-23) extracts from the Manuscript Records of the Collegiate Church of St. George at Windsor, from which it appears that John Prust (Canon of Windsor from 1379 to 1385) was paid £14, 9s. 3d. for six manuscripts written, illuminated, and bound, one of them with gold or silver clasps or bosses. The six books were an _Evangeliarium_, a _Martyrologium_, an _Antiphonale_, and three _Processionals_.
