In the early period textiles were especially important, used for church vestments, shrouds, hangings and clothing for the elite.

, though George T. Beech states that there is only one documented battle that William fought in Spain, and it occurred towards the end of his life. However, Beech adds that William and his father did have Spanish individuals within their extended family, and that while there is no evidence he himself knew Arabic, he may have been friendly with some European Christians who could speak the language. Others state that the notion that William created the concept of troubadours is itself incorrect, and that his "songs represent not the beginnings of a tradition but summits of achievement in that tradition."

and technologies from Spain into medieval Europe, where farming was mostly restricted to wheat strains obtained much earlier via central Asia. Watson listed eighteen crops, including sorghum from Africa, citrus fruits from China, and numerous crops from India such as mangos, rice, cotton and sugar cane, which were distributed throughout Islamic lands that, according to Watson, had previously not grown them. Watson argued that these introductions, along with an increased mechanization of agriculture, led to major changes in economy, population distribution, vegetation cover, agricultural production and income, population levels, urban growth, the distribution of the labour force, linked industries, cooking, diet and clothing in the Islamic world. Also transmitted via Muslim influence, a silk industry flourished, flax was cultivated and linen exported, and

grass, which grew wild in the more arid parts, was collected and turned into various articles.Andrew M. Watson (1974), "The Arab Agricultural Revolution and Its Diffusion, 700–1100", ''The Journal of Economic History'' 34 (1), pp. 8–35. However Michael Decker has challenged significant parts of Watson's thesis, including whether all these crops were introduced to Europe during this period. Decker used literary and archaeological evidence to suggest that four of the listed crops (i.e. durum wheat, Asiatic rice, sorghum and cotton) were common centuries before the Islamic period, that the crops which were new were not as important as Watson had suggested, and generally arguing that Islamic agricultural practices in areas such as irrigation were more of an evolution from those of the ancient world than the revolution suggested by Watson.

, water clocks, Pulp (paper), pulp and paper, silk, and various advances in making perfume, were transferred from the Islamic world to medieval Europe. Fulling mills and advances in mill technology may have also been transmitted from the Islamic world to medieval Europe, along with the large-scale use of inventions like the suction pump, noria and chain pumps for irrigation purposes. According to Watson, "The Islamic contribution was less in the invention of new devices than in the application on a much wider scale of devices which in pre-Islamic times had been used only over limited areas and to a limited extent." These innovations made it possible for some industrial operations that were previously served by manual labour or draught animals to be driven by machinery in medieval Europe. The spinning wheel was invented in the Islamic world by 1030. It later spread to China by 1090, and then spread from the Islamic world to Europe and India by the 13th century. The spinning wheel was fundamental to the cotton textile industry prior to the Industrial Revolution. It was a precursor to the spinning jenny, which was widely used during the Industrial Revolution. The spinning jenny was essentially an adaptation of the spinning wheel.


Coinage

While the Coin#History, earliest coins were minted and widely circulated in Europe, and Ancient Rome, Islamic coinage had some influence on medieval European minting. The 8th-century English king Offa of Mercia minted a near-copy of Abbasid Caliphate, Abbasid dinars struck in 774 by Caliph Al-Mansur with "Offa Rex" centered on the reverse. The moneyer visibly had little understanding of Arabic, as the Arabic text contains a number of errors. In

, Malta and Southern Italy from about 913 tarì gold coins of Islamic origin were minted in great number by the Normans, Hohenstaufens and the early Capetian House of Anjou, Angevins rulers. When the Normans invaded Sicily in the 12th century, they issued tarì coins bearing legends in Arabic and Latin. The tarìs were so widespread that imitations were made in southern Italy (Amalfi and Salerno) which only used illegible "pseudo-Kufic" imitations of Arabic. According to Janet Abu-Lughod:
The preferred specie for international transactions before the 13th century, in Europe as well as the Middle East and even India, were the gold coins struck by Byzantium and then Egypt. It was not until after the 13th century that some Italian cities (Florence and Genoa) began to mint their own gold coins, but these were used to supplement rather than supplant the Middle Eastern coins already in circulation.


Literature

It was first suggested by Miguel Asín Palacios in 1919 that Dante Alighieri's ''Divine Comedy'', considered the greatest epic of Italian literature, derived many features of and episodes about the hereafter directly or indirectly from Arabic works on Islamic eschatology, such as the ''Hadith'' and the spiritual writings of Ibn Arabi. The ''Kitab al-Miraj'', concerning Muhammad's ascension to Heaven, was translated into Latin in 1264 or shortly beforeI. Heullant-Donat and M.-A. Polo de Beaulieu, "Histoire d'une traduction," in ''Le Livre de l'échelle de Mahomet'', Latin edition and French translation by Gisèle Besson and Michèle Brossard-Dandré, Collection ''Lettres Gothiques'', Le Livre de Poche, 1991, p. 22 with note 37. as ''Liber scalae Machometi'', "The Book of Muhammad's Ladder". Dante was certainly aware of Muslim philosophy, naming Avicenna and Averroes last in his list of non-Christian philosophers in Limbo, alongside the great Greek and Latin philosophers. How strong the similarities are to ''Kitab al-Miraj'' remains a matter of scholarly debate however, with no clear evidence that Dante was in fact influenced.
