This Bent Pyramid at Dahshur is a precursor to its famous cousins just up the road. Construction began with an incline of 52 degrees and then changed about midway up to a more cautious 43-degree incline. The reason for the change is not known for sure.
To continue at the original angle would have required a taller, heavier structure. Perhaps materials and manpower were running short. Perhaps the architect decided the lower levels would not support the height needed to maintain the sharper incline. Another theory is that the decision to reduce the angle was influenced by the collapse of the pyramid at Meidum, a slightly earlier attempt at a smooth-sided pyramid. In any case, the Bent Pyramid gives an intriguing glimpse into the development of architecture and engineering in our mystery country over 4,500 years ago.
