the seventh. That is, the month Tisri, the seventh month of their ecclesiastical year, but the first of their civil year, answering to our September. This, which was their new year's day, was a time of great festivity, and ushered in by the blowing of trumpets; whence it was also called the feast of blowing the trumpets. In imitation of this Jewish festival, different nations began the new year with sacrifices and festivity. The ancient Egyptians did so; and the Persians also celebrated their new year's day, which they held on the vernal equinox, and which lasted ten days, during which all ranks seemed to participate in one general joy. The rich sent presents to the poor; all were dressed in their holiday clothes; all kept open house; and religious processions, music, dancing, a species of theatrical exhibition, rustic sports, and other pastimes, presented a continued round of varied amusement. Even the dead, and the ideal beings were not forgotten; rich viands being placed on the tops of houses and high towers, on the flavour of which the Peris, and spirits of their departed heroes and friends, were supposed to feast. After the Mohammedan conquest of Persia, the celebration of this period sensibly declined, and at last totally ceased, till the time of Jelaladdin, about A.D.

1082 who, coming to the crown at the vernal equinox, re-established the ancient festival, which has ever since been celebrated with pomp and acclamations.

The monthly sacrifices were regulated by the new moons; and it is probable that the solemn sacrifices were appointed by God, to prevent the idolatry which was usual among the heathen at this period; who expressed the most extravagant rejoicings on the first appearance of the new moon. Moses, however, used the return of the moon only as one of the most natural and convenient measures of time; and appointed sacrifices to Jehovah, to prevent the Israelites from falling into the idolatries of their heathen neighbours. In the serene climate of Arabia and Judea, its first faint crescent is, for the most part, visible to all. blowing
