Adelard of Bath
Adelard of Bath (; 1080 1152 AD) was a 12th-century English natural philosopher. He is known both for his original works and for translating many important Arabic and Greek scientific works of astrology, astronomy, philosophy and mathematics into Latin from Arabic versions, which were then introduced to Western Europe. He is known as one of the first to introduce the Arabic numeral system to Europe. He stands at the convergence of three intellectual schools: the traditional learning of French schools, the Greek culture of Southern Italy, and the Arabic science of the East.
Arabic parts
Beginning in the tenth century, many Arabic manuscripts were translated into Latin, becoming the means by which Classical astrology found its way back to Europe. Medieval astrologers, most notably the major 13th-century Italian, Guido Bonatti, a contemporary of Dante, assumed it was the Arabs who originated the concept of the lots, and hence they came eventually to be called the "Arabic parts".
