father to rank us among his friends.’ Upon hearing this, Demetrius accepted their presents, and raised the siege.” The city was, in the time of Augustus, the residence of a monarch, and considered the capital of Arabia Petræa. The country was conquered by Trajan, and annexed by him to the province of Palestine. In more recent times, Baldwin I. king of Jerusalem, having made himself also master of Petra, gave it the name of the Royal Mountain. The probability that the ruins of Wady Mousa are those of ancient Petra, is thus stated by Colonel Leake:—“The country of the Nabatæi, of which Petra was the chief town, is well characterised by Diodorus as containing some fruitful spots, but as being, for the most part, desert and waterless. With equal accuracy, the combined information of Eratosthenes, Strabo, and Pliny, describes Petra as falling in a line drawn from the head of the Arabian gulf (Suez) to Babylon; as being at the distance of three or four days from Jericho, and of four or five from Phœnicon, which was a place now called Moyeleh, on the Nabatæan coast, near the entrance of the Ælanitic Gulf; and as situated in a valley of about two miles in length, surrounded with deserts, inclosed within precipices, and watered by a river. The latitude of 30° 20´, ascribed by Ptolemy to Petra, agrees moreover very accurately with that, which is the result of the geographical information of Burckhardt. The vestiges of opulence, and the apparent date of the architecture at Wady Mousa, are equally conformable with the remains of the history of Petra found in Strabo, from whom it appears that, previous to the reign of Augustus, or under the latter Ptolemies, a very large portion of the commerce of Arabia and India passed through Petra to the Mediterranean, and that _armies_ of camels were required to convey the merchandise from Leuce Come [Leukè Komè], on the Red Sea, through Petra, to Rhinocolura, now El Arish. But among the ancient authorities regarding Petra, none are more curious than those of Josephus, Eusebius, and Jerome, all persons well acquainted with these countries, and who agree in proving that the sepulchre of Aaron in Mount Hor was near Petra. From hence it seems evident that the present object of Mussulman devotion, under the name of the tomb of Haroun, stands upon the same spot which has always been regarded as the burying-place of Aaron; and there remains little doubt, therefore, that the mountain to the west of Petra is the Mount Hor of the Scriptures; Mousa being, perhaps, an Arabic corruption of Movra, where Aaron is said to have died.”
