St Peter at Prayer, from the circle of Dutch artist Hendrick Bloemaert (1601/1602–1672). This prayer opened the Sarum Use of the Roman communion service, that is, a local variation on the Roman liturgy associated with Salisbury. At one time there were several such variant ‘Uses’, including Durham and York, but the Counter Reformation abolished them. The English reformers also abolished them, substituting the severely pared down Book of Common Prayer in 1549. As an English translation the Prayer Book was masterly, and nineteenth-century scholars who revived interest in the Sarum Use borrowed from it gratefully.
