In a period when Europe was plunged in the deepest barbarism, the light and splendor of Asia may be ascribed to the docility rather than the knowledge of the Turkish conquerors. An ample share of their wisdom and virtue is due to a Persian vizier, who ruled the empire under the reigns of Alp Arslan and his son.
