Diabolic designs?

Strange designs have appeared on the floor of the Roman building. Vandalism by a devil worshiping clique? Thankfully not, its just the mosaic design being laid out, following a design from Hurcot villa with slight modification from a simialr design from Hadspen villa to help make it fit it in the room. Meanwhile the Tesserae Totaliser keeps creeping up towards its targets, with the experimental work also solving questions such as mortar colour and depth.
