Two kinds of tile were used to create this mosaic, found on the floor of a room thought to be a “tablinum” (reception room). Tiny square ones make up the Greek key or “swastika” border, while lozenge-shaped ones create an optical illusion of 3-D cubes, similar to an M.C. Escher painting. The floor in the dining room of our hotel in Valletta had a modern reproduction of this same central pattern. Everything old becomes new again.
