@meadow_wind the sessions can sometimes be a starting place to do further research and
@Laura has written many books that are full of research that elucidate the sources for her questions in the sessions.
If you have not read it yet
The Secret History of the World and How to Get Out Alive is one of those books that may give you more sources to expand on this session and many others.
There are 14 references to Petrie in the above book. There are a resources mentioned in the bookmarks for books written by Petrie like:
[89]: Petrie,
Researches in Sinai, p. 166.
And in the bibliography:
Petrie, Flinders. 1906. Researches in Sinai. London: John Murray Publishers.
Hope this may help.
