"The kind of mind that designed the pyramids and the massive temples and walled cities represented a new human type, capable of effecting the abstract organization of complex functions in a structural design whose final form determined every stage in the work. The minds that solved these problems and carried out these designs were obviously minds of the highest order, with a unique combination of theoretical analysis, practical grasp, and imaginative foresight: Imhotep, who built the first stone pyramid at Sakkara, was a minister of state, an architect, an astronomer, and a physician. No narrowly trained specialists or 'experts' these, but men who moved freely over the entire area of existence, like the great artists of the Italian Renascence." - (Mumford, L (1967). Technics and Human Development.)
