Opus isodomum is a term used in architecture to describe a construction technique where the stones or bricks used in a wall are laid in regular courses of equal height. A similar term is "ashlar masonry", which refers to the use of cut and squared blocks of stone. Another possible synonym is "coursed masonry", which indicates that the wall is built with courses or layers of materials that have a uniform thickness. Other terms that can be used to describe opus isodomum include "regular masonry", "uniform masonry", or simply "plain masonry". These terms all describe the same basic technique, and can be used interchangeably depending on the context.
