They were supplanted by one of those adventurers so frequent in the annals of the East, who left his trade of a brazier (from whence the name of Soffaride.s) for the profession of a robber, xhe sosa In a nocturnal visit to the treasure of the prince of Sistan, 872962 Jacob, the son of Leith,^-*'" stumbled over a lump of salt, which he unwarily tasted with his tongue. Salt, among the Orientals, is the symbol of hospitality, and the pious robber immediately retired without spoil or damage.

From the height where he stood, the descent would not have been so soft or harmless : a timely death secured his own re- [a.d. sts] pose and that of the caliph, who paid with the most lavish concessions the retreat of his brother Amrou to the palaces of Shiraz and Ispahan.
