Life and work at the Great pyramid during the months of January, February, March, and April, A.D. 1865 with a discussion of the facts ascertained
Life and work at the Great Pyramid is a scholarly survey published in Edinburgh in 1867 by Charles Piazzi Smyth, the Astronomer Royal for Scotland, reporting his 1865 fieldwork on the monument for a learned audience. The three plates are technical diagrams: a plan enlarging the passage layout with dotted construction lines, a vertical section of the pyramid with sight lines and labelled axes, and a star map of the northern sky with the meridian and pole marked in red and black. A designer might borrow their precise linework, dense lettering arrangements, and the geometric clarity of overlaid guide lines.
