consolidation of English as a written language, taking over from French or Latin in certain areas, but a large shift from primarily theological or religious subject matter to also include that of a more secular nature. Vernacular book production saw a growth in the number of books being copied, both secular and religious. Thus, the latter portion of the 14th century can be seen as one of the most significant periods in the history of the English language. The reputation of Chaucer's successors in the 15th century has suffered in comparison with him, though Lydgate, Thomas Hoccleve, and Skelton are widely studied. At this time the origins of Scottish poetry began with the writing of The Kingis Quair by James I of Scotland. The main poets of this Scottish group were Robert Henryson, William Dunbar, and Gavin Douglas. Henryson and Dunbar introduced a note of almost savage satire, which may have owed something to the Gaelic bardic poetry, while Douglas's version of Virgil's Aeneid is one of the early monuments of Renaissance literary humanism in English. It was a vibrant time for religious drama as well: many morality plays and miracle plays were produced, and some scripts survive today. Sidrak and Bokkus is another example of late Middle English literature. Caxton and the English language In the late 15th century the first English printer, William Caxton, printed four-fifths of his works in English. He translated a large number of works into English; Caxton translated 26 of the titles himself. Caxton is credited with printing as many as 108 books, 87 of which were different titles. However, the English language was changing rapidly in Caxton's time and the works he was given to print were in a variety of styles and dialects. Caxton was a technician rather than a writer and he often faced dilemmas concerning language standardisation in the books he printed. (He wrote about this subject in the preface to his Eneydos.) His successor Wynkyn de Worde faced similar problems. Caxton is credited with standardising the English language (that is, homogenising regional dialects) through printing. This facilitated the expansion of English vocabulary, the development of inflection and syntax and the ever-widening gap between the spoken and the written word. However, Richard Pynson, a Frenchman who started printing in London in 1491 or 1492 and who favoured Chancery Standard English, was a more accomplished stylist and consequently pushed the English
