At the end of the 1400s, the world changed. Two key dates can mark the beginning of modern times. In 1485, the Wars of the Roses came to an end, and, following the invention of printing, William Caxton issued the first imaginative book to be published in England - Sir Thomas Malory's retelling of the Arthurian legends as Le Morte D'Arthur. In 1492, Christopher Columbus's voyage to the Americas opened European eyes to the existence of the New World. New worlds, both geographical and spiritual, are the key to the Renaissance, the 'rebirth' of learning and culture, which reached its peak in Italy in the early sixteenth century and in Britain during the reign of Queen Elizabeth I, from 1558 to 1603.
