A plan of the excavations of the Great Sphinx of Giza carried out in 1817 by Giovanni Battista Caviglia. The plan differs from modern plans in several ways. The Roman staircase to the east of the Sphinx has now been completely removed, as have most of the mudbrick walls erected by Thutmose IV illustrated here to its west. In addition, the plan does not include any of the surrounding temples that had yet to be discovered.
