The two most famous of the Rogan plates, Catalogue No. A91117 (Rogan Plate 1) and A91113 (Rogan Plate 2), Department of Anthropology,
NMNH,
Smithsonian, were interred as a pair and are very similar to one another. They were discovered in 1885 in a
stone box grave by
John P. Rogan during excavations of Mound C at the Etowah near
Cartersville, Georgia. The first is approximately and the second in height. Holes in the plates suggest they were once hung as decorations. These plates are stylistically associated with the Greater Braden Style and are thought to have been made in
copper workshops at
Cahokia (in Illinois near modern
St Louis) in the 13th century. The two plates depict a character known as the "
Birdman or falcon dancer", a figure now identified as representing the Upper World in the Southeastern Ceremonial Complex (S.E.C.C.). Each of the figures is in an energetic stance, possibly dancing. They have upraised right arms holding ceremonial stone maces and lowered left arms holding severed heads. On the figures' heads are elaborate headdresses with bi-lobed arrow motifs (identical to copper plate pieces also found at the site) and beaded forelocks. On the front of the headdress, in the forehead area, is a rectangular object, thought by scholars to represent a
sacred medicine bundle. Each figure has a long sash hanging from a belt and a motif known as the "bellows apron" attached at the waist. This is thought to represent a "
scalp", as the ornament has the same sort of bundle as the figures wear in their hair (although of a slightly different design), attached to a shape interpreted as hair. The faces of the severed heads have the
forked eye motif, in contrast to the faces of the figures. Archaeologist James Brown has argued since the 1990s that many of the attributes of the figure depicted with the Rogan Plate coincide with the
cultural hero Red Horn, described in the
oral history of
Ho-Chunk (and the related
Iowa and
Otoe-Missouria),
Chiwere Siouan–speaking Indigenous peoples originating in
Wisconsin. A second plate represents "fighting birds"; it somewhat resembles the Wulfing B or double-headed avian plate. The plates have been associated with the introduction of a new religion into the Etowah area during the
Early Wilbanks Phase (1250–1325 CE). The formerly abandoned site was suddenly repopulated and the residents began a new building scheme of
platform mounds and elite burials. This new religion relates to the later reported
Muskhogean myth of the Cult-Bringer. Anthropologists, ethnohistorians and archaeologists have identified the religion with the S.E.C.C. The Cult-Bringer is an anthropomorphic supernatural being who comes to the
Muscogee people and brings a new religion, lives with the people for a time, and imparts his wisdom to them before dying. This being is directly linked to brass and copper plates said to have been imbued with supernatural power. The elite of Etowah based their political power on this new ideology and used it as a mythical charter for their control over their society. Using the themes of physical prowess, fertility, and the afterlife, they identified with the Birdman ideology and displayed this symbolically through the wearing of special
shell gorgets and the repoussé copper plates. Since the majority of the copper plates found in Mound C were near the skulls of the buried remains, archaeologists believe they were used as headdresses. ==Other Etowah plates==
