George Stow was a Victorian man of many parts- poet, historian, ethnographer and prolific writer. A geologist by profession, he became acquainted, through his work in the field, with the extraordinary wealth of rock art paintings in the caves and shelters of the South African interior. Enchanted and absorbed by them, Stow set out to create a record of this creative work of the people who had tracked and marked the South African landscape decades and centuries before him. Unconquerable Spirit reveals for the first time the beauty and scope of his labors.
