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, published in Edinburgh in 1867 by Charles Piazzi Smyth, the Astronomer Royal for Scotland, records his 1865 survey fieldwork and interior measurements for a scholarly readership. The plates are measured architectural drawings: plans, sections and elevations of passages, galleries and chambers, drawn in fine hatching on cream paper, useful to a designer for technical diagram layouts, cross-hatching and engraved line work.
