The associations produced by national airs, and illustrated by the effect of the _Rans des Vaches_ upon the Swiss, are too well known to be related; and the _mal de pays_, or _nostalgia_, is an affection aggravated by the fond airs of infancy and youth during the sad hours of emigration, when the aching heart lingers after home and early ties of friendship and of love. It is somewhat singular, but this disease is frequent among soldiers in countries where they are forcibly made to march: but is seldom, if ever, observed in the fair sex, who most probably seek for admiration in every clime, and are reconciled by flattery to any region. The whims of musical composers have often been most singular; Gluck composed in a garden, quaffing champaign; Sarti, in a dark room; Paesiello, in his bed; Sacchini, with a favourite cat perched upon each shoulder. The extraordinary fancies of Kutswara, composer of the "Battle of Prague," are too well known, and led to his melancholy, but unpitied end. Great as the repute of the most popular musical performers, whether vocal or instrumental, in the present day may be, and enormous as their remuneration may seem, the ancients were more profuse in their generosity to musicians and the factors of musical instruments. Plutarch, in his life of Isocrates, tells us that he was the son of Theodorus, a flute-maker, who had realized so large a fortune by his business, that he was able to vie with the richest Athenian citizens in keeping up the chorus for his tribe at festivals and religious ceremonies. Ismenias, the celebrated musician of Thebes, gave three talents, or 581_l._ 5_s._ for a flute. The extravagance of this performer was so great, that Pliny informs us he was indignant at one of his agents for having purchased a valuable emerald for him at Cyprus at too low a price, adding, that by his penurious conduct he had disgraced the gem. The vanity of artists in those days appears to have been similar to the present impudent pretensions of many public favourites. Plutarch relates of this same Ismenias, that being sent for to play at a sacrifice, and having performed for some time without the appearance of any favourable omen in the victim, his employer snatched the instrument out of his hand, and began to play himself most execrably. However, the happy omen appeared, when the delighted bungler exclaimed that the gods preferred his execution and taste. Ismenias cast upon him a smile of contempt, and replied, "While _I_ played, the gods were so enchanted that they deferred the omen to hear me the longer; but they were glad to get rid of _you_ upon any terms." This was nearly as absurd as the boast of Vestris, the Parisian dancer, who, on being complimented on his powers of remaining long in the air, replied, "that he could figure in the air for half an hour, did he not fear to create jealousy among his comrades."
