Looking at Two Patterns Inspired in Coffered Ceilings: Some Examples in the Portuguese Roman Mosaics

Abstract

For the present study, we selected a set of Portuguese Roman mosaics in which the orthogonal grid compositions and adjacent octagons forming squares are present, supposedly inspired by the coffered ceilings. Therefore, in this study we try to ascertain: 1. Their degree of proximity to the pattern of the ceilings that have originated them; 2. Their relationship with other patterns and decorative motifs, occurring in the same mosaic pavement; 3. Their relationship with the functionality of the architectural space in which they are integrated. In the interweaving of this data and given the timelines of the different mosaics, we will try to elaborate conclusions on the application of these patterns to certain architectural spaces; the frequency of their use, either alone or in conjunction with other patterns in the same mosaic; the possible link of the mosaics in which these patterns occur with local or regional workshops, or even schools.
