 Dickeson, an amateur archaeologist, made hundreds of drawings of burial sites along the Ohio and Mississippi Rivers between 1837 and 1844. He commissioned Egan to paint this panorama based on Dickeson's sketches of Mississippi Valley excavations ["The River: Images of the Mississippi." Minneapolis: Walker Art Center, 1976, p. 32-34]. The panorama was first exhibited in Philadelphia in 1851.
 Dickeson took his panorama on the road, showing it to the public for twenty-five cents. He eventually presented it, along with his collection of artifacts, to the Academy of Natural Sciences [Silverberg, Robert. "Mound Builders of Ancient America: The Archaeology of a Myth." Greenwich: New York Graphic Society, 1968, p. 98-99].
 According to information provided by The University Museum in Philadelphia, the panorama was given to The University Museum around 1899, along with Dickeson's archaeological collection [SLAM document files].
