Some of the tiles from the villa were found to have impressions preserved
upon them. We have numerous examples of scored crosses, to mark the
position of nail holes perhaps, or possibly batch tally marks. We have
several examples of fingerprints left by the tilers as they moved the
wet tiles to the drying racks. We also have examples of footprints left
by dogs running over the tiles as they dried. One can imagine a first-century
AD tiler hurling abuse and possibly missiles at an errant dog as it
created an unwanted impression.
