virtuous, and if they be depraved, the people also will be depraved: even princes and men of learning.' And it is said by a certain sage, 'There are three kinds of kings, the king of the Faith, the king who watches over and protects those things that are entitled to respect and honour, and the king of his own inclinations. The king of the Faith constrains his subjects to follow the laws of their faith, and it behoves that he be the most pious of them all, for it is by him that they take pattern in the things of the Faith; and the folk shall do obedience to him in what he commands in accordance with the Divine ordinances; but he shall hold the discontented in the same esteem as the contented, because of submission to the Divine decrees. As for the king of the second order, he upholds the things of the Faith and of the world and compels the folk to follow the Law of God and to observe the precepts of humanity; and it behoves him to conjoin the sword and the pen; for whoso goeth astray from what the pen hath written, his feet slip, and the king shall rectify his error with the edge of the sword and pour forth his justice upon all men. As for the third kind of king, he hath no religion but the following his own lusts and fears not the wrath of his Lord, who set him on the throne; so his kingdom inclines to ruin, and the end of his arrogance is in the House of Perdition.'

The first seal was that of the sea and the police and of prohibition, and on it was written, 'Alternatives.' The second was the seal of revenue and of the receipt of monies, and on it was written, 'Culture.' The third was the seal of the commissariat, and on it was written, 'Plenty.' The fourth was the seal of (the Court of Enquiry into) abuses, and on it was written, 'Justice.' And these remained in use in Persia until the revelation of Islam. King Chosroes also, wrote to his son, who was with the army, 'Be not over-lavish to thy troops, or they will come to have no need of thee; neither be niggardly with them, or they will murmur against thee. Do thy giving soberly and confer thy favours advisedly; be liberal to them in time of affluence and stint them not in time of stress.' It is said that an Arab of the desert came once to the Khalif Mensour[FN#32] and said to him, 'Starve thy dog and he will follow thee.' When the Khalif heard his words, he was enraged, but Aboulabbas et Tousi said to him, 'I fear that, if some other than thou should show
