The Etowah plates, including the Rogan Plates, are a collection of Mississippian copper plates discovered in Mound C at the Etowah Indian Mounds near Cartersville, Georgia. Many of the plates display iconography that archaeologists have classified as part of the Southeastern Ceremonial Complex (S.E.C.C.), specifically "Birdman" imagery associated with warriors and the priestly elite. The plates are a combination of foreign imports and local items manufactured in emulation of the imported style. The designs of the Rogan plates are in the Classic Braden style from the American Bottom area. It is generally thought that some of the plates were manufactured at Cahokia (in present-day Illinois near St Louis, Missouri) before ending up at sites in the Southeast.
