Economic Botany and ethnobotany in al-Andalus (Iberian Peninsula: Tenth-fifteenth centuries), an unknown heritage of Mankind

The Hispano-Arabic culture in the Iberian Middle Ages is a major chapter in the history of the use and knowledge of plants. The Andalusi agronomists, botanists and physicians assimilated their heritage of Iberian, Hispano-Roman, and Hispano-Visigothic cultures with North-African and Eastern influences. They developed a profound knowledge of the plant world and managed a high diversity of species. A part of this ethnobotanical and agronomic heritage was transmitted not only to the local cultures and generations that followed, but also to peoples on the other side of the Atlantic Ocean by the Spanish colonists in the New World. This paper presents a study of the principal works of the so-called Andalusi Agronomic School (10th-15th centuries) and their agronomist authors: Arib ben Said, Ibn Wafid, Ibn Hayyay, Abu l-Jayr, Ibn Bassal, al-Tignari, Ibn al-Awwam and Ibn Luyun. We also raise questions about Andalusi ethnobotany, the introduction of Oriental species in the Iberian Peninsula and the prospects for ethnobotanical research through the philological study of Hispano-Arabic writings.
