In the latter part of the reign of Ptolemy VIII Euergetes II (145-116 B.C.E.), thus two synagogues were founded In Xenephyris, near Damanhur, and in Nitriai (modern Wadi Natrun or, more probably, el-Barnugi) in the Western Delta (CIJ II, Nos. 1441-1442; Horbury-Noy, Nos. 24-25). Other synagogues were founded by individuals, either personally or in affiliation with a group; families occasionally furnished the necessary equipment for a house of prayer. These cases are illustrated by two inscriptions from Athribis (today Tell Atrib, near Benha) in the Delta, dating from the second or the first century B.C.E.
