Fray Íñigo de Mendoza, reputedly Isabella's favourite preacher, is also one of the most important poets of the latter half of the fifteenth century; but no critical edition of his works exists, and no one to my knowledge has yet made a critical examination of the existing materials for it. A recent article by Antonio Pérez Gómez has cleared up some difficulties by unravelling the confusion of errors surrounding the first two editions of Mendoza's Vita Christi; but since these errors are all too liable to be perpetuated by the continued use of works such as the standard bibliographies, and since I have some comments to add, I shall not apologize for beginning again at the beginning while pursuing the story further.
