The first great English translation was the Wycliffe Bible (ca. 1382), which showed the weaknesses of an underdeveloped English prose. Only at the end of the 15th century did the great age of English prose translation begin with Thomas Malory's Le Morte Darthuran adaptation of Arthurian romances so free that it can, in fact, hardly be called a true translation. The first great Tudor translations are, accordingly, the Tyndale New Testament (1525), which influenced the Authorized Version (1611), and Lord Berners' version of Jean Froissart's Chronicles (152325).
