This evening at work I've been looking for resources to redesign my blog template which has led to some browsing of old Egyptology books, including Methods and Aims in Archaeology by William Matthew Flinders Petrie. I'm mostly looking for images, but this block of text caught my eye.
I have a feeling I might need to go through this whole book and post some of the highlights in the future.
ETA: Holy shit, I never noticed before that Petrie is holding a Predynastic beaker in that portrait. Durrrr.
