Roman brick stamps are different from stamps from other places and other uses because of the wealth of information found on them. The stamps included the name of the brick maker, the place the bricks were made, and the date. Brick makers were then able to be held liable for the quality of buildings made with their bricks. Sometimes these same stamps are found on other large clay products. The information contained on the individual bricks has been a tremendous boon to archeologists and architectural historians.
