||The Myth and Mystery of the Piasa Petrograph
Dr. Duane Esarey, Illinois State Archaeological Survey
Lost accounts and contradictory details have made painted images on the rock bluff at Alton, Illinois, an enduring source of mystery. Jollietâ€™s original 1673 drawing was supposedly lost, the paintings disappeared before authoritative renderings were captured, and local accounts of the imagesâ€™ meaning were badly confused. This presentation verifies a contemporary drawing fitting the description of Marquetteâ€™s account as coming from Louis Jolliet and uses a Peoria Indian culture-hero account to decode the long-lost meaning of the Piasa. In the process, a new supernatural character shows how similar imagery from Mississippian and earlier cultures must be reinterpreted. FREE. For more info: (217) 586-2612 or email@example.com.
