The museum itself is small, including floor mosaics of about 250 square meters, or about 2700 square feet. But archaeologists estimate that only one-seventh to one-eighth of the floor remains. To put that into perspective, we are talking about nearly half an acre of mosaic flooring. That’s something like an area from the 50 yard line to the goal line on an American football field. Archaeologists have suggested that it may have taken 80 million tesserae, the small, square tiles of limestone, glass, and ceramic that make up the mosaics.
