Legends surround the life of Osman; his dream of a great tree which should overshadow the world, of Constantinople won by clashing swords, of the ring of universal Empire, his romantic love suit, belong perhaps to history, but only as it appears magnified by an imagination fired by the wonderful successes of later years. More certain are the capture of Nicaea and of Brusa, accomplished by his son,--the latter still the picture of a Turkish city, with its innumerable mosques, its trees and gardens, its population half-military, but now wholly languid and quiescent. The sword of Osman is still the sign of power among his descendants. It rests in the türbeh of Eyûb, the companion of Mohammed himself, who fell not by the sword but by disease during the first Moslem attack on Constantinople in 672, and over whose grave Mohammed the Conqueror built a tomb, to the Moslems the most sacred of all in the city they had made their own. Osman was brought to Brusa only to be buried. His son Orchan carried fire and sword nearer and nearer to the goal. It was he who founded the terrible corps of the Janissaries, Christian child captives trained by the sternest methods to be the fiercest champions of Islam. In 1326 Orchan captured Nicomedia; in 1330 he defeated the imperial host led against him by the Emperor himself, and Nicaea fell into his hands. He showed the wisdom and restraint which, combined with the daring and ferocity of his men, served to strengthen the Turkish power step by step in the districts it won. Nicaea was not pillaged. Its citizens were allowed to live on in peace under Moslem laws, and Orchan himself by every act of charity and of devotion to his religion sought, and won, the respect of the people whom he had conquered. Then for twenty years he rested and prepared. Brusa was enriched with mosques and hospitals, tombs of soldiers and prophets, fountains, baths, colleges of students of the Koran. There rest to-day the first six Sultans, among "some five hundred tombs of famous men, pashas, scheiks, professors, orators, physicians, poets, musicians."
