(a.), the ass. Tame ( al-ahlī) and wild ( al-waḥs̲h̲ī, al-faraʿ) are distinguished. Some of the tame asses are beasts of burden, others are ridden; many of the latter are very swift. The ass can find its way again by a road even though it has only traversed it once before; its hearing is keen and it suffers little from disease. The ass is of special importance in Persia, Syria and Egypt. Many Arabs will not ride an ass out of pride, and it is not considered proper to mention the ass by its real name in go…

Its medicinal benefits were as an antidote against poisons and snake bites, if ingested alone or mixed with honey, and as an ointment for the cure of boils and abscesses, including haemorrhoids.

(A.; du persan pīl), éléphant. Le mot apparaît dans le titre et le premier verset de la sourate CV qui fait allusion à l’expédition d’Abraha [ q.v.], mais les Arabes ne connaissaient guère cet animal qui vit dans l’Inde et en Afrique, au point que, vers la fin du IIe/début du VIIIe siècle, le passage à Baṣra d’une troupe d’éléphants est un objet de curiosité pour la population (voir al-Nawawī, Tahd̲h̲īb, 738). Il en est déjà question dans Kalīla wa-Dimna (trad. A. Miquel, Paris 1957, 53), mais le premier auteur arabe à s’y intéresser vraiment et à se livrer à une enquête p…

, turquoise, pierre précieuse renommée allant du vert clair ou «cendre verte» au bleu ciel, avec un lustre semblable à celui de la cire, et composée d’un phosphate — contenant une quantité minime, mais essentielle, de cuivre et de fer. La couleur n’est point persistante dans toutes les pierres, et elle serait particulièrement attaquée par la sueur. Elle est presque toujours taillée, comme ornement, en cabochon, c’est-à-dire avec une surface convexe; seules les pierres qui portent une inscription…

(a.) «serpent», nom générique des ophidiens s’appliquant à toutes sortes de reptiles ( mā yansāḥ) des plus venimeux aux plus inoffensifs, la vipère ( apʿā) paraissant en être l’espèce la mieux différenciée. Des termes tels que ḥanas̲h̲, aym, t̲h̲uʿbān, aswad, raḳs̲h̲āʾ, sill, etc. désignent en arabe ¶ classique des espèces qui De sont pas toujours aisément identifiables d’après les descriptions figurant dans les anciens ouvrages de zoologie, car une certaine confusion règne dans ce domaine; la terminologie actuelle est encore loin d’être pr…

Ḥimār

(A.), âne (fém. atān et ḥimāra). Les Arabes distinguent l’âne domestique ( ahlī) et l’âne sauvage ( waḥs̲h̲ī, faraʾ, ʿayr al-ʿāna). Les ânes domestiques servent à faire tourner les moulins et sont utilisés comme bêtes de somme et montures, mais, bien que le Prophète en ait possédé un, nommé Yaʿfūr, et que des personnages célèbres aient apprécié son allure, les Arabes de qualité ne montent pas cet animal et emploient même une formule d’excuse ( ḥās̲h̲ā -kum, aʿazza-kum Allāh, etc.) quand ils prononcent son nom. Les ouvrages de zoologie fournissent des détails sur ses carac…

, Abū Bakr ibn Badr, surnommé al-Bayṭār al-Nāṣirī, fut grand maître et vétérinaire en chef des écuries du sultan mamlūk d’Égypte al-Nāṣir, Nāṣir al-dīn Muḥammad b. Ḳalāwūn (qui détint le pouvoir en 693/1294,698-708/1299-1309-10 et 709-41/1310-41). C’est sur la demande de ce prince qu’Ibn al-Mund̲h̲ir rédigea, vers 740/1339-40, son traité d’hippologie intitulé Kās̲h̲if hamm al-wayl fī maʿrifat amrāḍ al-k̲h̲ayl, somme compilée de sources antérieures et notamment du Kāmil al-ṣināʿatayn (al-bayṭara wa-l-zarṭafa) d’un certain Ibn Ak̲h̲ī Ḥizām ou Ibn Abī Ḵh̲azzām du IIIe/IXe ou d…

, perle. L’antique légende de son origine se trouve tout au long dans les auteurs arabes, d’abord dans le Lapidaire d’Aristote, puis, avec des variantes, chez les Ik̲h̲wān al-Ṣafāʾ et chez les cosmographes postérieurs. D’après cette légende, l’Aṣṭārūs (ὀστρεῖoν) s’élève des profondeurs de la mer sillonnée par les navires et va trouver Okeanos. Mais voilà que les vents soulèvent un embrun, et la coquille s’ouvre pour en recevoir quelques gouttes. Lorsqu’elle les a recueillies, elle se retire dans…

Ḥadīd

(a.), fer. D’après la Sūrat al-Ḥadīd (VII, 25), Dieu a envoyé le fer sur la terre pour le mal et le bien des hommes, car on en fait des armes et des outils. D’après la croyance des Sabéens [voir Ṣābiʾa], il est consacré à Mars. C’est le plus dur et le plus solide des métaux, et c’est le plus résistant à l’action du feu, mais c’est celui qui s’oxyde le plus facilement. Il est attaqué par les acides; en effet, avec l’écorce fraîche de la grenade, il donne un liquide noir (observation du fer attaqué par l’acide tannique); avec le vinaig…
