In the course of the survey of the northern concession of the Czechoslovak Institute of Egyptology, three repeatedly plundered rock tombs were discovered in 1964 near the village Naga el-Fariq. In tomb no. 2 (antechamber and burial chamber) many decorated and inscribed fragments of two sandstone sarcophagi, which are now deposited in the Náprstek Museum in Prague, were found.
Their owners had Egyptian names Betaref and Nebnisuttawy. Judging from the type of both sarcophagi, the architectural design of the tomb, the pottery sherds as well as the type of a shabti of baked clay, they could be dated back to the late 18th Dynasty (Nebnisuttawy) and the early 19th Dynasty (Betaref).
Both were members of a small Egyptian community from Naga el-Fariq probably kept in action (cca 1370 - 1250 BCE) a certain watch or control point situated above the Nile. From here the Egyptian expeditions continued to the south to reach the great fortress of Kubban and, along the desert road, some of Egypt's richest gold mines in the Wadi Allaqi.
