Pyramids, Photography, and Pseudoscience

Although Piazzi Smyth’s strange ideas about the pyramids represented the part of his career that was the least respected by his professional colleagues, they are perhaps still today what he is best known for by the general public. What were his ideas, and why were they so controversial?
