The region may have been used by the Nubians as a base for raids on southern Egypt.[26] Around 275 BC, Ptolemaic forces invaded Nubia and annexed the northern twelve miles of this territory, subsequently known as the Dodekaschoinos ('twelve-mile land').[27] The conquest was publicly celebrated in the panegyric court poetry of Theocritus and by the erection of a long list of Nubian districts at the Temple of Isis at Philae, near Syene.[28][29] The conquered territory included the rich gold mines at Wadi Allaqi, where Ptolemy founded a city called Berenice Panchrysus and instituted a large-scale mining programme.[30] The region's gold production was a key contributor to the prosperity and power of the Ptolemaic empire in the third century BC.[29] ./cache/en-wikipedia-org-4690.html ./txt/en-wikipedia-org-4690.txt
