Now, if he had great thoughts, was the time to make them known; now, if he felt disquieted about the gross idolatry of the people, was his chance to bear witness against it; now, if he wanted to revolutionize the old-world life of Mecca, he had his vantage ground from which to do so. But instead, during those fifteen years, from twenty-five to forty, so full and strenuous in the life of most men of action, Mohammed played no conspicuous part,--the years passed by, and on none did he write his name. [Sidenote: Rebuilding of the Kaaba.] Of many incidents recovered by Mohammedan historians in later days from the scrap-heap of small provincial history, and filled by them with portent and meaning, one at least is worth recalling. It reveals a touch of that capacity for manipulating men and circumstances which contributed so largely to Mohammed's power in later days. When he was in his thirty-fifth year, one {27} of those sudden, sweeping floods to which all mountain districts are liable swept through Mecca, and struck the Kaaba, tearing a hole in the wall, damaging the contents, and imperilling the roof. To the superstitious Meccans it was a portentous omen, and they waited expectantly for some dread visitation of the wrath of the gods whose shrine had been thus desecrated. As time passed and no calamity befell them, and less superstitious, or less reverent thieves took advantage of its insecure condition to pillage the shrine and plunder the sacred relics, the leading men of Mecca met in solemn conclave and decided that the Kaaba must be rebuilt. News reached them of a Grecian ship wrecked on the Red Sea shores not very far away. The timbers of the broken ship were bought, and her Greek captain, who had some reputation as an architect, was requisitioned to direct the building. The work was entered upon with great trepidation, but when once the ruined walls had been taken down without any visitation upon the workmen or the town, the work of rebuilding was eagerly begun, and the various clans of the Koreish vied with one another for what {28} they began to think the gods might after all consider zeal of religion and not sacrilege. The tribes of the Koreish were divided into four parties, to each of which one wall was assigned; stones of grey granite from the neighbouring hills were carried on the citizens' heads; soon the walls began to assume their old familiar shape, and all went harmoniously.
