Seetzen's ambition, like that of Burckhardt subsequently, was an expedition to Central Africa, but he wished previously to make an exploration of Palestine and Syria, to which countries attention was shortly to be directed by the "Palestine Association," founded in London in 1805. Seetzen did not wait for this period, but in 1802 set out for Constantinople, furnished with suitable introductions. Although many pilgrims and travellers had successively visited the Holy Land and Syria, the vaguest notions about these countries prevailed. Their physical geography was not determined, details were wanting, and certain regions, as for example, the Lebanon and the Dead Sea had never been explored. Comparative geography did not exist. It has taken the unwearied efforts of the English Association and the science of travellers in connexion with it to erect that study into a science. Seetzen, whose studies had been various, found himself admirably prepared to explore a country which, often visited, was still in reality new. Having travelled through Anatolia, Seetzen reached Aleppo in May, 1802. He remained there a year, devoting himself to the practical study of the Arabic tongue, making extracts from Eastern historians and geographers, verifying the astronomical position of Aleppo, prosecuting his investigations into natural history, collecting manuscripts, and translating many of those popular songs and legends which are such valuable aids to the knowledge of a nation. Seetzen left Aleppo in 1805 for Damascus. His first expedition led him across the provinces of Hauran and Jaulan, situated to the S.E. of that town. No traveller had as yet visited these two provinces, which in the days of Roman dominion had played an important part in the history of the Jews, under the names of Auranitis and Gaulonitis. Seetzen was the first to give an idea of their geography. The enterprising traveller explored the Lebanon and Baalbek. He prosecuted his discoveries south of Damascus, and entered Judea, exploring the eastern portion of Hermon, the Jordan, and the Dead Sea. This was the dwelling-place of those races well known to us in Jewish history; the Ammonites, Moabites, and Gileadites. At the time of the Roman conquest, the western portion of this country was known as Perea, and was the centre of the celebrated Decapolis or confederacy of ten cities. No modern traveller had visited these regions, a fact sufficient to induce Seetzen to begin his exploration with them. His friends at Damascus had tried to dissuade him from the journey, by picturing the difficulties and danger of a route frequented by Bedouins; but nothing could stay him. Before visiting the Decapolis region and investigating the condition of its ruins, Seetzen traversed a small district, named Ladscha, which bore a bad reputation at Damascus on account of the Bedouins who occupied it, but which was said to contain remarkable antiquities.
