In 1972, Dr. Todd Copley lived for a year in the remote highlands of South-West Ethiopia, with the Deemay people, who were still producing iron by methods used over 2000 years ago. In this talk, we will travel back to the African Iron Age to learn about the , the importance of iron not just for tools but in warding off the "evil eye", the day to day life of the Deemay, and the position of the smith caste in society. The role of inclusion analysis in determining patterns of trade in iron artifacts will be discussed.
