Biodeterioration of Polychrome Roman Mosaics

PROTECTING ONE OF THE BEST ROMAN MOSAIC COLLECTIONS IN THE WORLD: Ownership and Protection in the Case of the Roman Mosaics from Zeugma, Turkey

Unraveling Roman mosaic meander patterns: A simple algorithm for their generation

A geometrical analysis of the meander decorative patterns on a Roman pavement mosaic found at the Roman villa in Chedworth, England, is presented. The analysis reveals that the intricate swastika meander pattern consisting of four closed curves could have been easily constructed using a very simple hypothesized algorithm. The algorithm also explains the design of Roman swastika meanders found t...

Gemini alkylammonium salts as biodeterioration inhibitors.

To protect materials against biodeterioration, physical, biological or chemical methods can be used. Chemical inhibitors of biodeterioration are the most common and effective. A new class of chemical inhibitors-gemini alkylammonium salts-shows excellent biocidal properties and good ecological profile. These compounds can be applied as biodeterioration inhibitors in a wide variety of materials.

Agriculture in Roman Britain

I F we consider that agriculture employed a majority of the population in non-industrial societies and is still man's staple occupation, we must ad-mit that the agriculture of Roman Britain has concerned archaeologists and historians much less than it should, for on its vicissitudes depended to no small degree the well-being and decline of the province. The existence of Roman 'villas' was first...

Combining Statistical Tools and Ecological Assessments in the Study of Biodeterioration Patterns of Stone Temples in Angkor (Cambodia)

Biodeterioration is a major problem for the conservation of cultural heritage materials. We provide a new and original approach to analyzing changes in patterns of colonization (Biodeterioration patterns, BPs) by biological agents responsible for the deterioration of outdoor stone materials. Here we analyzed BPs of four Khmer temples in Angkor (Cambodia) exposed to variable environmental condit...
