I went to a very good talk at the little Petrie Museum around the corner from Gower Street on the 19th January.
'HARN member, Amara Thornton (Institute of Archaeology, UCL) explores
the connections between sites and seances in early twentieth century
archaeology. Concentrating on the archaeologists George Horsfield and
Agnes Conway but with reference to Petrie’s assistant and lecturer at
UCL Margaret Murray, Dr Thornton considers how the use of mediums and
psychical research was a larger phenomenon in archaeology than has
generally been admitted.'
