Sphinx of Hatshepsut (18th Dynasty Female Pharaoh) 

This statue shows the pharaoh Hatshepsut (18th Dynasty) represented in sphinx form. Although the Great Sphinx of Giza is generally understood to depict a male ruler, examples like this demonstrate that the sphinx form itself was not exclusively male in ancient Egyptian art.
