 Most pyramids and mastabas contain sections which are cut into ground level, and there are full rock-cut tombs in Egypt that date back to the Old Kingdom.After the defeat of the Hyksos and the reunification of Egypt under Ahmose I, the Theban rulers began to construct elaborate tombs that reflected their newfound power.The tombs of Ahmose and his son Amenhotep I (their exact location remains unknown) were probably in the Seventeenth Dynasty necropolis of Dra' Abu el-Naga'.
