Two interesting large tiles molded in relief using plastic clay. One tile depicts Mercury, a major god in Roman religion and mythology. The other tile depicts Nehalennia, a goddess of the sea, of unclear origin, perhaps Germanic or Celtic. Tile are marked at the front with: M (Mercurius) and N for Nehalennia. At the bottom left a small makers mark that I do not recognize. Excellent condition tiles. I do not know the factory or artist who made these.
