Burckhardt remained at Aleppo from September, 1809, to February, 1812, pursuing his studies of Syrian manners and customs, and of the language of the country, with but one interruption, a six months' excursion to Damascus, Palmyra, and the Hauran, a country which had hitherto been visited by Seetzen only. It is related that, during an excursion into Gor, a district north of Aleppo, upon the shores of the Euphrates, the traveller was robbed of his baggage and stripped of his clothes by a band of robbers. When nothing remained to him but his trousers, the wife of a chief, who had not received her share of the spoil, wished to relieve him even of those indispensable garments! The _Revue Germanique_ says:--"We owe a great deal of information to these excursions, respecting a country of which we had only crude notions, gained from Seetzen's incomplete communications. Burckhardt's power of close observation detected a number of interesting facts, even in well-known districts, which had escaped the notice of other travellers. These materials were published by Colonel Martin William Leake, himself a geographer, a man of learning, and a distinguished traveller." Burckhardt had seen Palmyra and Baalbek, the slopes of Lebanon and the valley of the Orontes, Lake Huleh, and the sources of the Jordan; he had discovered many ancient sites; and his observations had led especially to the discovery of the site of the far-famed Apamoea, although both he and his publisher were mistaken in their application of the data obtained. His excursions in the Auranitis were equally rich, even though coming after Seetzen's, in those geographical and archaeological details which represent the actual condition of a country, and throw a light upon the comparative geography of every age. Leaving Damascus in 1813, Burckhardt visited the Dead Sea, the valley of Akaba, and the ancient port of Azcongater, districts which in our own day are traversed by parties of English, with their _Murray_, _Cook_, or _Baedeker_ in their hands; but which then were only to be visited at the risk of life. In a lateral valley, the traveller came upon the ruins of Petra, the ancient capital of Arabia Petraea. At the end of the year Burckhardt was at Cairo. Judging it best not to join the caravan which was just starting for Fezzan, he felt a great inclination to visit Nubia, a country rich in attractions for the historian, geographer, and archaeologist. Nubia, the cradle of Egyptian civilization, had only been visited, since the days of the Portuguese Alvares, by Poncet and Lenoir Duroule, both Frenchmen, at the close of the seventeenth century, at the opening of the eighteenth by Bruce, whose narrative had so often been doubted, and by Norden, who had not penetrated beyond Derr.
