It was to the Moorish capital that students of the medical art repaired who desired to master the latest discoveries and most modern methods in the treatment of the human body. Irrigation with the Moors had become an applied science, and was employed extensively throughout the Iberian peninsula with the most advantageous results in enhancing the fertility of the soil. Nowhere else in Europe did the land yield such rich harvests, and nowhere else was the science of agriculture so fully understood. The fertile fields of those days are in many cases replaced by barren deserts and the towns with teeming populations by ruins and uninhabited wastes. The ignorant peasantry that has taken the place of the cultivated sons of Arabia are still in the matter of civilisation and commercial activity hundreds of years behind the busy and intelligent population whom in the latter part of the fifteenth century they finally drove over the seas after subjecting them to the most cruel persecution for adhering to the faith of their fathers. Three million Moors are said to have been ejected from Spanish soil at the bidding of the civil power, instigated by ecclesiastical tyranny. Civilisation has not yet rallied from the so-called “triumph of the Cross” in Spain. This ejection of the Moors from the west of Europe coincided, as it happened, with the advent of the Turk at Constantinople; but here, by a curious contradiction, the Turk as the champion of Mohammedanism represented not progress but the triumph of the sword. The case was inverted, but in each instance it represented the victory of barbarism over civilisation, whether the Mohammedan made headway in the east or the Christian in the west. In the east the effete remnant of the Eastern Empire was swept away before the advancing hosts of Islam. In the west a far more highly developed and industrial population was wiped out at the bidding of the myrmidons of the Papal See. For five hundred years the Moors had ruled all but the northernmost portion of Spain, and for another 250 they retained the province of Granada. Countless examples of their ornate and characteristic semi-oriental architecture remain behind as a record of their artistic culture, and much also of their language intermingled with that of the race which they at first conquered and which in the days of their luxury and decadence reconquered them in turn. But the intellectual life of Moorish Spain, which was for so long like a beacon light in the darkness of Mediæval Europe, has passed, never to return. The Inquisition marked the high-water mark of the reaction of Christian bigotry against the tolerant and broad-minded intellectuality which had flourished under the fostering dominion of a race whose glories to-day are but a memory of the far-distant past.
