Around 150 AD Claudius Ptolemaeus wrote the great handbook of astronomy, later known as the Almagest, which became the prevalent handbook for the knowledge of the stars in Europe for about 1500 years. The text was handed on to the Europeans through Arabic translations in the ninth century AD, and translated into Latin in the twelfth century.

The peoples of the Islamic world excelled at designing and building water-clocks as these manuscripts show.

During a period often characterised as one of decay and decline, the Andaluso-Tunisian astronomer Ibn al-Raqqām wrote his Risālah fī ‘ilm al-ẓilāl, the most important treatise on sundials of the Islamic West. The instruments he describes are much more elaborate and sophisticated than the surviving examples of Medieval sundials from al-Andalus and the Maghrib.

Among pre-modern Arabic scholars, the Almagest was generally regarded as the most authoritative work on astronomy. This esteem for Ptolemy's text, however, contrasted with a common practice among Arabic readers not to consult the Almagest directly but to rely on later commentaries for studying Ptolemy's theories.

Mathematicians in medieval Islamic societies were the first to grasp the real significance of Menelaus’ Spherics. They followed Menelaus’ approach to spherical geometry and went on to develop spherical trigonometry as an independent branch of mathematics.

How did a fourteenth century illustrated ‘Treatise on the Art of Riding and using the Instruments of War’ end up in the British Library’s Arabic manuscript collection? A ‘Nincumpoop’ of the Napoleonic era, who moonlighted as an antiquarian, holds the answer.

A 1787 letter requesting plants from the Persian Gulf for a newly established botanical garden in Kolkata illuminates the way in which the pursuit of scientific knowledge became part of the EIC’s global economic endeavour.

al-Bīrūnī’s Qānūn is the most complete astronomical encyclopedia of the Middle Ages. It represents the most successful attempt to correct and rewrite Ptolemy’s Almagest, and was based on the results of three centuries of research in Islamic lands.

In the ninth century, Ḥunayn ibn Ishāq decided to explain Greek terminology, instead of simply adopting it, in his translations of the medical treatises of Galen. In doing this he helped establish Arabic as an international language of science.

Ḥunayn Ibn Isḥāq: a Medieval Arab scholar who transformed his understanding of ancient Greek medical texts into manuals for the benefit of many successive generations of students.

An enormous effort was made to translate almost all known Greek literature into Arabic during the 8th to 10th centuries, and Baghdad was at the centre of this work. Why was it that so many of the translators were Christians?

In 1920, a gift from Ibn Saud in the form of a female oryx was the first ever to have survived the difficult journey from Arabia to London.

Viewed alternately as both luxury and necessity, ice has been valued in warm climates for millennia. Technological advances altered methods of producing, storing, and using ice, but it remained a highly sought-after and regulated product well into the twentieth century.

For eight hundred years, the Arabic scientific tradition was superior to that found in western Eurasia. It gave birth to new theories and fields of scientific inquiry that laid the foundations for the Scientific Revolution, and continued to flourish thereafter.
