In short, the only system of decoration which, with the exception of Calligraphy, borrows nothing from Nature: geometrical ornament--from which the Greek and Latin races merely derived poor and frigid effects--became endowed with real life. Henceforward this decoration was significantly labelled as Arabesque and, following the example of its model, it tried skilfully to astonish the mind by straying in the midst of the most inextricable entanglements and unexpected transformations.... How precious are the creations of Moslem art! European amateurs nowadays outbid each other in golden offers for its vestiges, hoping through them to introduce into their homes a few gleams of the mirages that inspired their authors. Radiant stained-glass, variegated glassware, stuffs worked with gold or silver wire, sparkling silks, damaskeened, inlaid bronzes, exquisite miniatures in the dwellings of the West, do they not all sing the glory of Islam? Among all these treasures, connoisseurs already begin to prefer those of Calligraphy which animates the transcription of the divine verses by the delicate colouring of copies of the Qur'an, or of the thick enamel of earthware. By so doing, the buyers of Europe follow the example of Mussulman princes of the best epoch who, to possess a page of calligraphy by a celebrated artist, lavished madly as much money as is given in our time for masterpieces of painters. May not these sacred inscriptions, causing their new possessors to be thrilled with admiration by reason of the refined elegance of their form, reveal one day to their purchasers the sublime beauty of the Islamic soul lurking in these writings? [Sidenote: INFLUENCE OF MOSLEM CIVILISATION IN EUROPE DURING THE MIDDLE AGES AND THE RENAISSANCE] Even at a period when Europe was not inimically inclined towards Islam, it was dazzled by all its marvels and borrowed largely from the decorative and architectural genius of the Arabs. Deep research would soon prove that it owes much more to it than to Greek or Latin antiquity. Such a study would take us too far from our subject. We may, however, point out as a curious fact that, according to the historian Dulaure, Arab architects were employed in the work of building the Parisian cathedral of Notre Dame. In the domain of science, the influence of the Moslems was just as fertile. To give an idea thereof, we cannot do better than summarise the opinion vouchsafed by Doctor Gustave Le Bon, in his remarkable work: _La Civilisation des Arabes_. (_The Civilisation of the Arabs._) "First of all, it must be acknowledged that it is to the Arabs that we owe entirely the idea of experiment and observation, the basis of modern scientific methods, overriding the authority of a master. This substitution is therefore not the work of Bacon, to whom it is generally attributed.
