Answer:
Centers of great learning and art
Preserved much of Greek knowledge
Explanation:
During the Islamic Golden age, that encompasses from the 7th century AD until the 14th century AD, Islamic caliphates preserved much of the writings and studies of the ancient Greek philosophers and mathematicians, and also Islamic universities and centers of learning pushed the study of nature, science, and the development of technology and arts. In fact, the Abbasid Caliphate, with its capital in Baghdad, created the House of knowledge, in charge of translating the texts of ancient Greeks, but also the books and manuscripts from India, China, and other regions. Since in Islam it is forbidden to reproduce images of humans and animals, Islamic Empires developed a unique form of art focused on extremely ornamented geometry, which is reproduced in paintings, architecture, and writing across the Islamic world.
