This is a portrait triad of three of the ancient Nile Valley's mightiest matriarchs. From left to right, we have the Ptolemaic Queen Cleopatra VII, the Egyptian Pharaoh Hatshepsut, and Kentake Amanirenas of Kush.

With this one I was playing with a "triangular" composition, or a composition with the three subjects arranged like points on a triangle (i.e. one in the background and two in the foreground).
