Abstract

Due to its early Christianization, Armenia has preserved a huge patrimony of religious figures in paintings, statues, icons and illuminated codices. Most of the latter are still conserved in Matenadaran Library in Yerevan and their chronology is widely represented from the Middle Ages to XIX century. Armenian manuscripts embrace also various humanities, such as history, philosophy, law, medicine and mathematics. A rich historiographic literature is also present. Therefore it was attractive to carry out an attempt to discover materials and techniques used in the past to prepare the manuscripts and to assemble the codices. Inks and gilding were also considered. Specific materials of Armenian culture will be emphasized. The samples were taken by some of us at the Matenadaran Library of Yerevan (Armenia) and some additional materials, such as Armenian bole and cochineal powder, were found in Yerevan too. The samples were taken with a lancet on deteriorated portions of some papers and parchments pertaining to Armenian codices. Only small fragments were used, since the spectroscopic techniques used need amount down to some micrograms. This is due to their high spatial resolution, enabling also the overlapping layers of pigments and preparation to be studied and their molecular identity to be ascertained in a non-destructive non –invasive way: the same samples could be subjected to other analyses with other techniques. The use of so small samples enabled the use of high performance instrumentation in the Centre of Great Instruments in Modena (CIGS) and to carry out additional experiments with silver nano-particles for Sers technique (surface enhanced Raman spectroscopy). Fourier-Transform infrared (FTIR) spectra were recorded using an Alpha FT-IR spectrometer (Bruker) equipped with the Diffuse Reflection Infrared Fourier Transform ( DRIFT) module in the spectral range 7500 – 375 cm-1 at a resolution of 2 cm-1 cumulating at least 200 scans.
