Natural History and Geography

The vast expanse of the Islamic world enabled the Muslims to develop natural history based not only on the Mediterranean world, as was the case of the Greek natural historians, but also on most of the Eurasian and even African land masses. Knowledge of minerals, plants and animals was assembled from areas as far away as the Malay world and synthesized for the first time by Ibn Sina in his Kitab al-Shifa’(The Book of Healing). Such major natural historians as al-Mas’udi inter twined natural and human history. Al-Biruni likewise in his study of India turned to the natural history and even geology of the region, describing correctly the sedimentary nature of the Ganges basin. He also wrote the most outstanding Muslim work on mineralogy.

As for botany, the most important treatises were composed in the 12th century in Spain with the appearance of the work of al-Ghafiqi. This is also the period when the best known Arabic work on agriculture, the Kitab al-falahah, was written. The Muslims also showed much interest in zoology especially in horses as witnessed by the classical text of al-Jawaliqi, and in falcons and other hunting birds. The works of al-Jahiz and al Damiri are especially famous in the field of zoology and deal with the literary, moral and even theological dimensions of the study of animals as well as the purely zoological aspects of the subject. This is also true of a whole class of writings on the “wonders of creation” of which the book of Abu Yabya al-Qazwini, the ‘Aja’ib al-makhluqat (The Wonders of Creation) is perhaps the most famous.

Likewise in geography, Muslims were able to extend their horizons far beyond the world of Ptolemy. As a result of travel over land and by sea and the facile exchange of ideas made possible by the unified structure of the Islamic world and the hajj which enables pilgrims from all over the Islamic world to gather and exchange ideas in addition to visiting the House of God, a vast amount of knowledge of areas from the Pacific to the Atlantic was assembled. The Muslim geographers starting with al-Khwarazmi, who laid the foundation of this science among Muslims in the 9th century, began to study the geography of practically the whole globe minus the Americas, dividing the earth into the traditional seven climes each of which they studied carefully from both a geographical and climactic point of view. They also began to draw maps some of which reveal with remarkable accuracy many features such as the origin of the Nile, not discovered in the West until much later. The foremost among Muslim geographers was Abu ‘Abdallah al-Idrisi, who worked at the court of Roger II in Sicily and who dedicated his famous book, Kitab al-rujari (The Book of Roger) to him. His maps are among the great achievements of Islamic science. It was in fact with the help of Muslim geographers and navigators that Magellan crossed the Cape of Good Hope into the Indian Ocean. Even Columnbus made use of their knowledge in his discovery of America.
