Talking of music reminds me of a remark of the learned Gentius, in one of his notes on the _Gulistan_ of Saadi, that music was formerly in such consideration in Persia that it was a maxim of their sages that when a king was about to die, if he left for his successor a very young son, his aptitude for reigning should be proved by some agreeable songs; and if the child was pleasurably affected, then it was a sign of his capacity and genius, but if the contrary, he should be declared unfit.--It would appear that the old Persian musicians, like Timotheus, knew the secret art of swaying the passions. The celebrated philosopher Al-Farabi (who died about the middle of the tenth century), among his accomplishments, excelled in music, in proof of which a curious anecdote is told. Returning from the pilgrimage to Mecca, he introduced himself, though a stranger, at the court of Sayfu 'd-Dawla, sultan of Syria, when a party of musicians chanced to be performing, and he joined them. The prince admired his skill, and, desiring to hear something of his own, Al-Farabi unfolded a composition, and distributed the parts amongst the band. The first movement threw the prince and his courtiers into violent laughter, the next melted all into tears, and the last lulled even the performers to sleep. At the retaking of Baghdad by the Turks in 1638, when the springing of a mine, whereby eight hundred jannisaries perished, was the signal for a general massacre, and thirty thousand Persians were put to the sword, a Persian musician named Shah-Kuli, who was brought before the sultan Murad, played and sang so sweetly, first a song of triumph, and then a dirge, that the sultan, moved to pity by the music, gave order to stop the slaughter. To resume, after this anecdotical digression. Saadi gives this whimsical piece of advice to a pugnacious fellow: "Be sure, either that thou art stronger than thine enemy, or that thou hast a swifter pair of heels." And he relates a droll story in illustration of the use and abuse of the phrase, "For the sake of God," which is so frequently in the mouths of Muslims: A harsh-voiced man was reading the Kuran in a loud tone. A pious man passed by him and said: "What is thy monthly salary?" The other replied: "Nothing." "Why, then, dost thou give thyself this trouble?" "I read for the sake of God," he rejoined. "Then," said the pious man, "_for God's sake don't read_."
