Yes, it’s another tile. This is an unusual tile in many ways. The most common type of tile in the fourteenth century was the encaustic tile. Whereas the design on an encaustic tile was level with its surroundings, the design on a relief tile stood proud of its background. That immediately makes this one stand apart. The second thing is that, like the Tring Tiles, it retains most of its glaze.
When Robert of Golam was abbot, in the mid-twelfth century, the chapter house at the Benedictine St Albans Abbey was paved with relief tiles. Relief tiles were more common in Eastern Europe (Germany, Denmark, Poland) than in England.
This particular tile must have been in a part of the floor that received little use, for the glaze is mostly intact and the raised parts of the tile have barely been worn down at all.
Relief tiles are among the earliest found in ecclesiastical buildings. The Anglo-Saxons used them in the late tenth and early eleventh century, but they were rare. This one dates from the mid-twelfth century (1151-1166) when they became more common in churches and abbeys.
There are two types of relief tiles: relief and counter-relief. Relief tiles have a raised design, while counter-relief tiles have a raised background. The St Albans tile is a relief tile. Its design was stamped into the clay with a wooden or metal stamp.
