 The Renaissance was so called because it was a "rebirth" not only of economy and urbanization, but also of arts and science.It has been argued that this cultural rebirth was fuelled by massive rediscoveries of ancient texts that had been forgotten for centuries by Western civilization, hidden in monastic libraries or in the Islamic world, as well as the translations of Greek and Arabic texts into Latin.The migration west into Italy of intellectuals fleeing the crumbling Eastern Roman Empire at this time also played a significant part.
