The textile depicts a moment of the Divine Liturgy that precedes the Communion of the Apostles. It is an excellent and rare example of post-Byzantine ecclesiastic embroidery in the Dodecanese. Silk and metallic threads of various types have been used. Microscopic observation of the morphological characteristics of the threads was key for the better understanding of manufacturing the techniques and technology used in the artefact.

Six three-leaf stone masonry wallettes (scale 2:3) were tested in compression or in diagonal compression up to their maximum resistance. After unloading, they were grouted using either a ternary or a hydraulic lime grout. Subsequently, they were tested again in compression or in diagonal compression to failure. For both types of grout, the wallettes exhibited substantial improvement of their behaviour, in terms of compressive strength, tensile strength and reduction of the separation between the three leaves of masonry. The obtained results are presented and commented. MechanicalProperties of Three-Leaf Stone Masonry after Grouting chemical compatibility; therefore, its use is desirable, provided that it proves to be efficient from the structural point of view as well. The mix proportions of the grouts, along with their mechanical properties and injectability...

It was excavated during the Italian occupation and reconstructed by the Italians in the period 1937–8. The method of the “scenographic” restoration was the “mixed structure” technique using a core of reinforced concrete in combination with new biocalcarenite stones and the integration of very few ancient architectural members. Its proximity to the sea and the corresponding salt decay phenomena, aggravated by the erroneous reconstruction methodology and materials, have further deteriorated its state of preservation. Today, the four columns, epistyle and entablature of the Italian interventions demand immediate restoration actions to ensure the monument’s sustainability. This can only be achieved through a combined study of the performance of potential restoration materials and assessment of their compatibility with the historical materials. In the present st...
