An overview of conservatory mosaic protection models in ancient Salona – outdated solutions as a contemporary problem

During the last 40 years, since the first thematical congress dedicated exclusively to mosaic protection was held in Rome, the profession of conservation-restoration has advanced significantly in that field. In spite of this, we have still not dealt with the legacy left behind by actions taken before that period, and so on archaeological sites or in museum collections we often confront difficulties that haunted the mosaic caretakers during the time of the profession's original organisation: mosaic ensembles detached from its original backing without a detailed plan of protection, safekeeping and presentation, today often forsaken and deteriorating. The problem can in a local context be approached by studying the mosaical heritage of Salona, the provincial centre of Roman Dalmatia. Numerous investigators in Salona during the last two hundred years have attempted to go about these mosaics in different ways. Alongside the practice of conservation and in situ backfilling of large mosaical ensembles, some of them were detached and placed on difficult to move reinforced concrete bases which are, often within sub divo museum exhibits, rapidly deteriorating today. The aim of this paper is to offer a section view of the matter, one that provides information about conservation- restoration techniques in certain historical circumstances, past and present solutions for detached mosaics, as well as contemporary challenges and presentation models of mosaics separated from their native surroundings. With the material capabilities of our time, and technological solutions that grow more varied and accessible by the day, the question is if we can repair the previously inflicted damage? After exhibiting basic facts about the previousli treated mosaics, the paper suggests some of the most modern solutions of virtual, and even augmented presentation, with which we are able to recreate the original context of the detached mosaic, even in situations where it had previously been compromised, or even destroyed.
