As well as traditional religion, Wallinger's work has sometimes referenced myths. "Ghost" (2001) is a negative print of George Stubbs' famous horse painting "Whistlejacket" that has had a horn added to its head, thus turning it into a unicorn. Originally planned as a full-scale painting, time constraints meant the piece was manipulated entirely in Photoshop from high quality side scans. "Time and Relative Dimensions in Space" (2001) takes a more modern myth as its subject - it is a life-sized mirrored model of the TARDIS from "Doctor Who" which at certain angles seems to blend into its environment.
