 Cerball appears to be referenced in The Prophecy of Berchán, although not by name.Cerball is noted by historians to have been a patron of noteworthy building projects in his kingdom, and his reign likely birthed a flourishing of artistically fine stone carving in Osraige.In late February 2017, Kilkenny's new Medieval Mile Museum opened to the public, featuring an exhibit which highlights king Cerball's role as a powerful patron of Osraige's early high cross carving tradition.
