York Missal, folios 95v-96r

The missal was one of the most important texts for a medieval priest, containing the essential texts for the performance of mass. This rubricated missal was created for use in York and features the feasts of John of Beverley and William of York as well as passages for Yorkshire saints. The Canon page on folio 96r begins 'Te igitur clementissime pater...' (Thee, therefore, most merciful father...) and is opposed by the Ordinary of the mass, with musical notation and an unfinished miniature of the Crucifixion in colour and gold.
