Beside the bleak burgs, squalid ignorance and abysmal barbarism of Europe, Byzance isolated and fastidious, luxurious and aloof, learned and subtle, Roman in body but Greek in soul, contrasted almost supernaturally. Set apart from and beyond the mediæval night, her marble basilicas, her golden domes, her pineapple cupolas covered with colors, her ceaseless and gorgeous ceremonials, gave her the mysterious beauty of a city shimmering on uplands of dream. It was a dream, the final flower of Hellenic art. The people, delicately nurtured on delicate fare, exquisitely dressed in painted clothes, rather tigerish at heart but exceedingly punctilious, equally contemptuous and very well bred, must have contrasted too with the Crusaders. Contiguous was Persia which, taken by Muhammad, had, with but the magic wand of her own beauty, transformed his trampling hordes into a superb and romantic nation, fanatic indeed, quick with the scimitar, born fighters who had passed thence into Egypt, Andalusia, Syria, Assyria and beyond to the Indus. The diverse lands they had subjugated and united into one vast empire. Baghdad was their caliphate. Before the latter and on through the Orient were strewn in profusion the marvellous cities of the Thousand and One Nights, the enameled houses of the Thousand and One Days. There, in courtyards curtained with cashmeres, chimeras and hippogriffs crouched. The turbans of the merchants that passed were heavy with sequins and secrets. The pale mouths of the blue-bellied fish that rose from the sleeping waters were aglow with gems. In the air was the odor of spices, the scent of the wines of Shiraz. Occasionally was the spectacle of a faithless favorite sewn in a sack and tossed by hurrying eunuchs into the indifferent sea. The sight was rare. The charm of Scheherazade and Chain-of-Hearts prevailed. The Muslim might dissever heads as carelessly as he plucked an orange, they were those of unbelievers, not of girls. Among the peris of his earthly paradise he was passionate and gallant. It is generally in this aspect that he appears in the _Thousand and One Nights_, which, like the _Thousand and One Days_, originally Persian in design, had been done over into arabesques that, while intertwisting fable and fact, none the less displayed the manners of a nation. Some of the stories are as knightly as romaunts, others as delicate as lays; all were the unconsidered trifles of a people who, when the Saxons were living in huts, had developed the most poetic civilization the world has known, a social order which, with religion and might for basis, had a superstructure of art and of love. It was this that louts in rusty mail went forth to destroy. But though they could not conquer Islâm, the chivalry of the Muslim taught them how to conquer themselves. From the victory contemporaneous civilization proceeds.
