The Vitruvian overlay
Grant lays a cross-section of the Great Pyramid over Leonardo’s Vitruvian Man, about 1490, and matches the chambers and shafts to the horizontal lines Leonardo drew on the body.

The drawing is in the Gallerie dell’Accademia, Venice, and illustrates Vitruvius’s proportions of a man in a circle and a square. The pyramid’s interior was not surveyed until the nineteenth century. An overlay that fits can be made from many diagrams with horizontal lines; the question is what would fail to fit. No Leonardo scholar has adopted the match. It is the clearest example on this site of a reading made entirely of alignments.
