The Petrie Museum houses many small finds (from Hatshepsut) such as scarabs, foundation deposits, tools, vessel fragments.
Searching through their collection this evening i came across a foundation plaque (UC8532) which was found in excavations by Petrie at Hierakonpolis, Egypt. This is the first mention of this site i have been able to locate through my own research, so further details will follow once they become available to me.
Tomorrow i attend a day school about Petrie (good timing!). I may be able to find out about excavations by Petrie in this area. Certainly i will ask the right questions which will at least point me in the right direction.
To find out about modern excavations at Hierakonpolis, see Hierakonpolis Online and follow the links.
