The Abbasid Caliph Haroun-al-Rashid sent Charlemagne in Aix from Baghdad a present of a clock made by his horologists which struck a bell on the hour very hour, to the great wonder and delight of the whole court of the newly crowned Holy Roman Emperor.

The massacre and expulsion of the Muslims of Andalusia by the Christians carried with it the clousure of many of the great factories that has existed under Islamic rule, and the standstill of progress that had been made in science, crafts, arts, agriculture, and other products of civilization. Towns began to fall into ruin because of the lack of skilled masons. Madrid dropped from 400,000 to 200,000 inhabitants: Seville, which had possessed 1,600 factories under the Muslims, lost all but 300, and the 130,000 workers formerly employed had no more jobs, while the census of Philip IV showed a fall of 75% in population figures.

It was the Muslims also who brought about the substitution of cotton-wove paper for the old parchments; and it was this invention which formed the basis for Europe's later invention of printing, using an old Chinese technique, and so for the vast uprush of learning which came with the Renaissance. More, since monks were starved for parchment on which to write their religious works, they were tending more and more to scrape off priceless ancient scientific texts from old parchments and to use them again as palimpsets. The introduction of paper put a stop to this disastrous practice in time to save quite a number of texts which would have otherwise been lost for ever, as, alas, too many were.

A paper manuscript of the year AD 1009 was found in the Escorial library, and claims to be the oldest hand-written book on paper still in existence. Silk-wove paper, of course, was a Chinese invention, since silk was native to China though rare in Europe; and the Musulman genius lay in seeing the possibility of substituting cotton for silk, and so giving Europe a plentiful supply of a practicable material for the reproduction of books by the monkish scribes.

Philip Hitti writes in his "History of the Arabs" that the art of road-making was so well developed in Islamic lands that Cordova had miles of paved road lit from the houses on each side at night so that people walked in safety; while in London or Paris anyone who ventured out on a rainy night sank up to his ankles in mud - and did so for seven centuries after Cordova was paved! Oxford men then held that bathing was an idolatrous practice; while Cordovan students revelled in luxurious public hammams!
