It is written in the chronicles of the Sassanian monarchs that there once lived an illustrious prince, beloved by his own subjects for his wisdom and his prudence, and feared by his enemies for his courage and for the hardy and well-disciplined army of which he was the leader. This prince had two sons, the elder called Schah-riar, and the younger Schah-zenan, both equally good and deserving of praise. When the old king died at the end of a long and glorious reign, Schah-riar, his eldest son, ascended the throne and reigned in his stead. Schah-zenan, however, was not in the least envious, and a friendly contest soon arose between the two brothers as to which could best promote the happiness of the other. Schah-zenan did all he could to show his loyalty and affection, while the new sultan loaded his brother with all possible honors, and in order that he might in some degree share the sultan's power and wealth, bestowed on him the kingdom of Great Tartary.
