In this paper we will review the investigation of the material remains of floor, wall, and ceiling decorations at the Sorna site near Porec, and research of the documentation of data recorded in the course of archaeological excavations at the site. The remains of painted plaster and marble facing are discussed in detail, while mosaic surfaces are treated solely by way of an examination of the available photographic documentation. It is the intention of this paper to offer a possible interpretation of the appearance of the floor, wall, and ceiling decoration of the Roman period villa on the Sorna peninsula, based on existing fragments, documentation, and parallels to similar decorations in Roman villas across the empire. The proposed interpretations are, of course, conceptual and certainly subject to reinterpretation and supplementation. Publication Abstract
