Update: Return to the Great Pyramid

Accessed June 15, 2009 | Archaeology Magazine Online | by Bob Brier

Archaeology Magazine features Bob Brier's update on Houdin's internal ramp theory, where he and Houdin focus their attentions on an L-shaped room that could have been created deliberately for the construction of the Great Pyramid.

This article features nice pictures with descriptors and a link to Archaeology's previous update and a web site dedicated to the theory from Dessault Systemes.

How Where the Pyramids Built?

Originally published May 20, 2009 | Talk Pyramids Blog

This 6-part blog post on Talk Pyramids announces a new model at the Boston Museum that shows how the pyramids were built according to the external spiral ramp theory. Following this small blurb and accompanying photo, are a handful of other blog posts that describe previous theories on Egyptian pyramid building. They include:

1. Donald B. Redford's traditional theory, where a mud brick ramp was employed, oiled to help teams of oxen and men, not slaves, bring up blocks of limestone, and where local limestone served as the pyramid core and finer quality limestone as the casing
2. A docudrama from the BBC entitled Building the Great Pyramid.
3. John Romer's unique theory based on the traditional theory, documented in a video entitled Secrets of the Great Pyramid
4. The cement pyramid theory, first introduced by David Davidovitts, where he states that the Egyptians used limestone-based concrete to create perfectly formed blocks, using the Famine Stele as his proof. His theory was later supported by Michel Barsoum who proved it with science and by Linn Hobbs' team that tested the theory in creating their own concrete limestone block.
5. Jean-Pierre Houdin's internal ramp theory, inspired by the spiral ramp theory, that he hopes to prove with technology.
6. And Mark Lehner's theory that it was a band of Egyptians and not slaves who built the pyramids, using the remains of a "pyramid city" nearby as his evidence.
