A large complete Roman roof tile (tegula), rectangular in shape with side flanges to butt against adjacent tiles. On the top surface a neat semi-circle has been scribed while the clay is still damp and this is thought to be a workman's mark to identify his work for accounting purposes. There are also several paw prints across the surface, made by an animal (probably a dog) running across the tile when the tile was lying outside to dry before firing.
Roof tiles came in two standard types; one with angled sides that fitted alongside the next tile (tegula), while a curved tile (imbrex) of the same length was mortared over the joint to make it waterproof.
