The Egyptians continued to construct taller and taller pyramids and started smoothing out the jagged edges of stepped pyramids. One of the earliest attempts was the Meidum pyramid, in 2570 B.C. It had seven steps progressing to eight, but
Pyramid designers learned that if pyramids were going to be higher and have steeper slopes, their bases needed to be wider.
Unsatisfied with the Bent Pyramid, Sneferu ordered another pyramid at Dahshur. The designers chose a better foundation and made this pyramid the same height as the Bent Pyramid, but with a wider base and a shallower angle. The Red Pyramid was completed in 2560 B.C.
