By the year 600, and probably a considerable time before, the Koreish of Mecca had attained a curious and exceptional position. There, in an absolutely barren valley and near a spring of brackish water, a sanctuary stood. Some families of the Fihr clan, which belonged to the Bedouin tribe of Kinana, had settled round about it and established, under the name of Koreish, a lax commonwealth of the kind frequently found in Arabia. A considerable area in the immediate vicinity of their sanctuary may possibly have been respected as holy ground, in which no blood was to be shed, long before the Koreish took possession of it. Thus secured from harm, and held in high esteem as the guardians of the Kaaba (a small, square primitive house enclosed within a building open to the sky), the Koreish had turned their attention to commerce. They sent forth their caravans far and wide, as the Ishmaelites and Sabæans had done of old.[14] Koreishites travelled as merchants to Gaza, Jerusalem, and Damascus, to Hira on the Euphrates, to Sana in Yemen, and even crossed the Red Sea to Abyssinia. By these means they not only acquired considerable wealth according to Arab standards, but what was of much greater value--a wider mental horizon than the Bedouins and the inhabitants of the oases, and a knowledge of men and affairs. Although they never quite attained a regular political organisation, yet Wellhausen is right when he says, “We note something of an aristocratic hereditary wisdom, as in the case of ancient Rome and Venice.”[15]
