Although the decoration of monumental structures, especially churches, is relatively well-synthesised, this is not true of street porticoes, shops, workshops, and ordinary houses. In order to produce convincing urban images, we need to consider not only major public structures, but also in-between spaces. It is also necessary to have an idea of how such decoration, which might not attract as great an investment as public buildings, aged, weathered, and was repaired. The thesis will compile a gazetteer of dated examples of decoration for porticoes, modest houses, shops, workshops and small churches, with a thematic chapter on each, illustrated by a case study. The study will also consider evidence for light fittings, shutters, textile hangings etc, which might have modified the appearance of structures.
