The _Fifteen Oes_ itself is a most interesting book. It was printed originally, no doubt, as an extra part for an edition of the _Horæ ad usum Sarum_ now entirely lost. It contains a beautifully executed woodcut of the crucifixion,—one of a series of five which occur complete in a _Horæ_ printed by Wynkyn de Worde in 1494, and it is also the only existing book from this press which has borders to the pages. Caxton printed altogether about one hundred books, using in them altogether eight types. Blades gives ninety-nine books printed by Caxton, two of which were certainly printed by his associate in Bruges after Caxton had left for England. On the other hand, he does not mention the newly-discovered Grammar, the two editions of the Indulgence of 1489, a second edition of the _Lyf of our Lady_, known from a fragment in the Bodleian, and one or two other indulgences. One or two books which Blades includes were printed undoubtedly by De Worde, such as the _Book of Courtesye_ (which, indeed, contains his small device), _The Chastysing of God’s Children_, and the _Treatise of Love_. The genuine Caxtons catalogued by Blades number ninety-four. As regards types, Blades gives six of Caxton’s, and a seventh which he conjectures only to have been used by Wynkyn de Worde, though in this he was mistaken, for it occurs in books printed while Caxton was alive. Again, the type of the 1489 Indulgence which he does not mention, was conclusively proved by Bradshaw to be one of Caxton’s types. This type should be considered as type 7, and the former type, which does not appear until 1490-91, as type 8. The woodcut initials which occur in the _Chastysing of God’s Children_ were not used till after Caxton’s death. But while we venerate Caxton as our first printer, we must not overlook the claims which he has upon us as a translator and editor. Wonderful as his diligence in press-work may appear, it is still more wonderful to consider how much literary work he found time to do in the intervals of his business. He was the editor of all the books which he printed, and he himself translated no less than twenty-two, including that great undertaking the _Golden Legend_. Even on his deathbed he was still at work, as we learn from the colophon of the _Vitas Patrum_, printed by Wynkyn de Worde in 1495: ‘Thus endyth the moost vertuouse hystorye of the deuoute and right renowned lyves of holy faders lyvynge in deserte, worthy of remembraunce to all wel dysposed persones, which hath ben translated oute of Frenche into Englysshe by William Caxton of Westmynstre late deed and fynysshed at the laste daye of hys lyff.’
