| The Bent Pyramid of Snefru |
|
The South, or "Bent," pyramid was the second built by Snefru. It is thought that this is the first
pyramid ever designed and constructed as a true pyramid from the start. There is
general agreement that the pyramid took on its current form due to attempts to cope with subsidence and structural stresses. In
particular, the slope probably was changed from 54° (about that of the
Great Pyramid) to 44° (about that of the Red Pyramid) to reduce stress on
the inward-sloping stone courses of the lower structure. The change
in slope resulted in a 30% reduction in the mass of the upper portion of
the pyramid. The construction of the Red Pyramid, however, clearly indicates that, in the
end, these measures were not considered adequate. The pyramid's base
was originally 188 m square and it had a height of 105 m, giving it a
volume of 1.42 million cubic meters. Had the original design been
completed the pyramid would have been 129 m high and would have had a volume of 1.53 cubic meters.

Stela depicting Snefru found at the Bent Pyramid - now in the
Egyptian Museum courtyard in Cairo. Unlike the Red Pyramid, the pyramid complex at the Bent
Pyramid was completed. Therefore, although Snefru was probably buried in the Red, his cult
probably centered at the
Bent. |

The effects of weathering and pollution on the white Turah limestone
casing are clearly visible. |
