This roundel is carved in high relief in a style that is eye-catching and meant to be seen from a distance. It likely once adorned the exterior of an early church and would have been part of a larger design. The central medallion consists of a Christogram, an early symbol merging the first two letters of the word Christ in Greek, Χ (chi) and Ρ (rho). In the spaces between the left and right arms of the chi, are two additional Greek letters, α (alpha) and ω (omega). A laurel wreath surrounds the central medallion, and this is further surrounded by a vine motif consisting of alternating ivy and grape leaves.
