Two hundred and fifty copies printed. The two leaves, subsequently printed, giving an account of the sale of the edition at auction, at the upset price of £9 per set, should be added, "a result," says Mr. Sotheby "unparalleled in the annals of literature." One of the most important works ever produced upon the history of early printing, on which it throws great additional light. It contains an extended examination of the various editions of the block books (or books printed from wooden blocks), the earliest productions of the art, issued in Holland, Flanders, and Germany, such as the Apocalypsis S. Johannis, Biblia Pauperum, Ars Moriendi, Cantica Canticorum, Liber Regum, Temptationes Dæmonum, Ars Memorandi, Endkrist, Quindecim Signa, De Generatione Christi, Miribilia Romæ, etc. It is not, however, confined to a history of block books, for it gives minute accounts, accompanied by exact facsimiles, of some of the most interesting and rare works printed with movable type in the infancy of the art, such as the Donatuses, Doctrinale, Catonis Disticha, Horarium, Facetiæ, Morales, Speculum Humanæ Salvationis, Bartolomæus van de Proprietaten der Dinghen, Exhortatio contra Turcos, Literæ Indulgentiarum, etc.
