A total of twenty-one samples of historical colorful textiles, from a variety of Greek folklore regional costumes, were obtained from the Aristotle University Collection of Folklore Archive and Museum, Thessaloniki.
The first and major immediate-term research aim of the study was the identification of the textile fibers as well as of the study and the analytical investigation of the two metal threads among the samples, which was achieved through a combined application of microscopic techniques: Optical Microscopy (OM), Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray Spectrometry (EDS) at the University of Thessaloniki. Interesting to attain further and more detailed information only to some samples of them, we performed High Resolution-Transmission Electron Microscopy (TEM) at Centro Grandi Apparecchiature at Palermo, Italy. The observation through those multi-microscopic techniques led us to the unambiguous identification of wool, cotton, silk and hemp.
The second important aim was the dyes characterization which was carried out by using High-Performance Liquid Chromatography (HPLC-DAD), with Diode Array Detector, at the University Ecclesiastical Academy of Thessaloniki and Uv-Vis Diffuse Reflectance Spectroscopy (Uv-Vis DRS) at the Chemistry Department of Aristotle University of Thessaloniki. In addition, some samples were selected to investigate them by Fourier Transform Infrared Spectroscopy (FT-IR) and Raman Spectroscopy. The examination by all these analytical techniques, additionally allowed us a better insight in the advantages and limitations of these multiple analytical approaches and as well as assess their applicability to historical colorful textiles. Several of natural, synthetic and semi-synthetic dyes have been identified: Madder (Rubia Tinctorum L.), Red wood (pos. Caesalpinia echinata), Weld (Reseda Luteola L.), Persian Berries (Rhamnus sp.), Indigo (Indigofera Tinctoria L.), Indigo Carmine, Prussian Blue, by comparison with standards and reference materials.

In this study six thematic units referring to figurines of Sirens are developed: 1) Their production and dispersion, with particular reference to local clays, 2) the techniques of their manufacture, 3) typological and stylistic analysis of the material, 4) the workshops that were producing these particular figurines, 5) their function and their association with rituals relating to water, love and death (and mainly their funerary use), 6) their interpretation, as conclusion, the results of the exhaustive study of the subject are presented, with parallel reference both to the ancient Greek literary sources and the papyri, inscriptions and other sources. Examination of the particular stylistic and iconographic traits allows us to proceed to the typological classification of these figurines into five basic types. Although Sirens are first encountered in ancient Greek literature in Rhapsody xii of Homer’s Odyssey, and are identified as a motif in ancient Greek art by the eighth century BC, the provenance of these beings is certainly not Greek. Their conception as a subject is attributed to the influence of eastern models and specifically to the Egyptian concept of the soul, Ba. The material on which the study is based comes from excavations in various areas of the Aegean.
