Aleppo (ä-lěp′pō), a city of Syria, is built over the ancient city of Berœa. It is surrounded by a stone wall forty feet high and three and a half miles long. In an earthquake which occurred in 1822 two-thirds of the people were swallowed up. Outside the city beautiful gardens stretch for 12 miles to the southeast. The “boil of Aleppo” is a cancer that breaks out on the faces of children and lasts a year, leaving a scar for life, by which a citizen of the place can be easily recognized. Population, 210,000.
