The William Blake Archive is pleased to announce the publication of a digital edition of Jerusalem The Emanation of The Giant Albion Copy F, from the Morgan Library and Museum. Jerusalem is Blake’s masterpiece in illuminated printing, consisting of 100 relief and white-line etchings divided into four chapters. It is his longest illuminated book and its plates are among his largest, at approximately 22.5 x 16 cm. Though dated 1804 on its title plate, it was not printed in its entirety until c. 1820. Sixty plates may have been completed by 1807; a few examples were exhibited in 1812. The printing of 1820 produced Copies A, C, and D. In the next year, Blake printed Copies B (chapter 1 only, Plates 1-25) and E. Blake printed Copy F in 1827. Copies H-J are posthumous. Most lifetime copies have hand tinting in gray or black, but only Copies B and E are colored. There are two arrangements of the plates in chapter 2, early (Copies A and C) and late (Copies D and E).
