This book is about the remarkable transfer of knowledge from the Islamic world to Medieval Europe during the Islamic Golden Age (8C - 13C), a period of scientific, economic and cultural development. Baghdad became the centre of one of the greatest empires in history, with the House of Wisdom as its cultural centre, where scholars translated many ancient texts into Arabic from books collected from far away continents. When the Muslim world expanded to the shores of Europe, mathematicians, engineers, astronomers, philosophers and others brought their skills and knowledge with them, from which Early Renaissance scholars developed their own ideas for future scientific and cultural achievements.
