1,000 Years of Scientific Texts From The Islamic World Are Now Online
Between the 9th and 19th centuries, Arabic-speaking scholars translated Greek, Latin and even Sanskrit texts on topics such as medicine, mathematics and astronomy, fostering a vibrant scientific culture within the Islamic world.

The library, a joint project of the British Library and the Qatar Foundation, offers free access to 25,000 pages of medieval Islamic manuscripts. Among some of the most significant texts:
The Book of Knowledge of Ingenious Mechanical Devices (1206 A.D.), which was inspired by an earlier, 9th-century translation of Archimedes’ writings on water clocks. Devices such as the "Elephant Clock" were the most accurate time-keeping pieces before the first pendulum clocks were built in the 17th century by the Dutch scientist Christiaan Huygens.

This is one of the only three recorded copies of an influential treatise on the construction and use of astrolabes by Abū al-Rayḥān Muḥammad ibn Aḥmad al-Bīrūnī (973-1048), containing 122 diagrams.

Mecca, Saudi Arabia | Pléiades Satellite Image
"Mecca (Arabic: مكة‎) is a city in the Hejaz and the capital of Makkah Province in Saudi Arabia. The city is located 70 km (43 mi) inland from Jeddah in a narrow valley at a height of 277 m (909 ft) above sea level. Its resident population in 2012 was roughly 2 million, although visitors more than triple this number every year during Hajj period held in the twelfth Muslim lunar month of Dhu al-Hijjah."

"As the birthplace of Muhammad and a site of Muhammad's first revelation of the Quran (the site being a cave 3.2 km (2 mi) from Mecca), Mecca is regarded as the holiest city in the religion of Islam and a pilgrimage to it known as the Hajj is obligatory for all able Muslims. Mecca is home to the Kaaba, by majority description Islam's holiest site, as well as being the direction of Muslim prayer."
