An illuminated “E” depicting Christ presenting his mission to St Peter is believed to have been cut out of a Dominican antiphonary produced in Cologne in the first half of the 14th century. The initial, painted on vellum, is the first letter of the antiphon “Ecce ego mitto vos sicut oves in medio luporum” (“Behold, I send you as sheep in the midst of wolves”). It is for sale in Sotheby’s auction of important medieval manuscripts collected by the late Ernst Boehlen, on 2 July, with an estimate of £30-40,000
