How Many Pyramids Does One Man Need?

[Minimalist]

The king would built the "bent pyramid" had to have a second one done, IIRC.

I think sneferu had three built, the maidum pyramid, the bent pyramid, and the red pyramid.

The important thing is the three sneferu built were all big pyramids that were built on the grand Old Kingdom scale comparable to the great pyramids of Giza, not the feeble little wannabes of the middle kingdom like the two mentioned above.

Sneferu also ruled for at least 24 years and there are some indications that it was even longer.

Worse, take a close look at this photo of tourists climbing on the Red Pyramid.



Generally speaking you can count 3+ layers of masonry behind each person indicating that the individual stones were on the order of 1.5 feet wide.

Now contrast that with this photo from the Great Pyramid.



The individual stones are much larger and they fit together much better.  The GP is a whole order of magnitude superior in workmanship.
