The Governorate of ʿAjlun is the smallest governorate in today’s Jordan. It is located in north-west Jordan at 79 km north of ʿAmman, the capital of Jordan (fig. 1). ʿAjlun Governorate covers about 420 square km. It is renowned for its mountains, with one of the hightest in this area, at about 1,200 m above sea level, and for its castle called ʿAjlun Castle (formerly Al-Rabad castle). As in other parts of Jordan, some Greek inscriptions were discovered in the Governorate. They were published in different international journals. Elaborating on the idea of a corpus of Greek and Latin inscriptions in Syria initiated in the 1920s by father Louis Jalabert, the Department of Antiquities of Jordan authorized in 1970 the Institute Fernand-Courby in Lyon (France) to collect and publish the Greek and Latin Inscriptions discovered on the territory of the Hashemite Kingdom of Jordan. The name given to this part of the corpus is I. Jordanie (Inscriptions de la Jordanie = IGLS XXI).
