More often this herringbone pattern is referred to as
opus spicatum. It is a stone bond in the shape of a herringbone, and found in
carolingien (Carolingian) and
préroman (Pre-Romanesque) buildings. This bond is abundantly present in the walls of the Saint-Laurent in Tournus.
There is some confusion about this term in French Wikipedia. They distinguish "appareil en épi de blé" = stone bond in the shape of ears of wheat (
opus spicatum) and "arête de poisson". The difference is that in case of
arête de poisson the joint between the herringbones forms a straight line, while in
opus spicatum it follows a zigzag line.
The picture shows the only remainig bit of wall of the original Sainte-Marie in Bonnay.
