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 Yahya al-Qazwini, the 'Aja'ih al-makhluqat (The Wonders of Creation) is perhaps the most famous.
