"Ancient Egyptian civilization, and particularly its architecture, predatedEuropean, American (including Mayan and Aztecan) and Black African ar-chitecture. One of the most impressive Egyptian monuments remaining arethe pyramids. The existence of pyramidal influences in other cultures raisesthe difficult question of the social and historical production and diffusion ofbuilt form by built forms. By diffusion I mean the permanent dialectic be-tween borrowings and discoveries in two different societies or cultures.The historical and social production of Egyptian and Mayan pyramids will betraced In tight of why this pyramidal form and not others was produced, howthey were built and for whom, and why they were replicated in such coun-tries as: United States, Greece, France, Italy, and Mali. Historically, theEgyptian pyramids appeared earlier than the Mayan. For geographical rea-sons, It is almost impossible to make any kind of connection between them.However, the pyramlos found in Greece, Mali, Italy, ... France, and he Unit-ed States seem to have been one influence of Ancient Egypt. The social, eco-nomic, and political context in which these countries' architects built pyra-mids will be questioned. These architects replicated or used the Egyptianpyramidal form In their architecture without mentioning Ancient Egypt'contribution to world architecture in general. I will look at the implicationof these "borrowings" in new design and why the Egyptian origins are notcredited when they are placed in new environments."
