The SIU Seal
The Southern Illinois University Seal represents activities of the SIU System and is used by both SIU Edwardsville and SIU Carbondale. It features Old Main, one of the original buildings on SIUC’s campus that was destroyed by fire in 1970, and the Latin words Deo Volente, which translates “God willing.”
The Seal is used for formal documents such as diplomas and commencement materials and for materials from the Office of the President. Use on merchandise requires approval through Collegiate Licensing and approval by SIUC University Communications for uses related to SIUC.
