of substantial timber; and a fresh garrison of three thousand men was stationed at Petra to sustain the labors of a second siege. The operations, both of the attack and defence, were conducted with skilful obstinacy; and each party derived useful lessons from the experience of their past faults. A battering-ram was invented, of light construction and powerful effect: it was transported and worked by the hands of forty soldiers; and as the stones were loosened by its repeated strokes, they were torn with long iron hooks from the wall. From those walls, a shower of darts was incessantly poured on the heads of the assailants; but they were most dangerously annoyed by a fiery composition of sulphur and bitumen, which in Colchos might with some propriety be named the oil of Medea.
