This presentation aims at highlighting the main result of the petrographic and chemical analyses carried out on the samples collected from the Hellenistic strata and structures of Yeronisos island. A multidisciplinary approach involving a combination of chemical and physical analyses, as well as petrography, have been adopted in order to characterise the plasters and mortars of the site. The primary question behind this research was wether Yeronisos' samples would be in line with the products of the local industry, or wether this site was more influenced by the
Ptolemaic presence. In order to answer to this question, the Yeronisos set of samples has been compared with a coeval set collected from the Hellenistic Theatre in Nea Paphos.
During this conference, I will present the results of X-Ray diffraction, thermal analysis, physical and mechanical testing, petrographic observation and SEM analysis.
