The ring's dimensions, (bezel: length x width=2.7 x 1.7cm, hoop: width: 0,4cm, depth: 0,13cm) correspond to the ones given by the excavator in the 1933 publication (deviation by almost 1 mm.), as also does the representation on the bezel. The ring's weight is 10.26 gr (not given originally by the excavator), which corresponds well to the weight of several Mycenaean signet rings. The examination of the ring took place on Tuesday April 12th, in the Museum, where the undersigned and Ms Poulou were welcomed on behalf of the Museum's Director, by Ms Maria Dahlstrom, Curator and Ms Anna Fahlen, Collections Manager of the Museum; we were escorted to a quiet meeting room with suitable space where we would be able to study the signet ring that was brought to us immediately after. In the presence of the three ladies, we began to examine it, first macroscopically and then by using a handheld digital microscope Dino-Lite 5MP Edge AM7915MZTL, which we had brought with us from Greece and belonged to the equipment of the Metals Conservation Laboratory of the National Archaeological Museum, Athens. Along with the microscopic examination, we also used a digital precision balance (0.5kgr/0.01gr) for measuring the weight of the ring and a Sony a7 Full-Frame Mirrorless Digital Camera, in order to take as many digital photographs and details as possible. 2. Signet ring (back side of bezel) from the Tiryns Hoard, 12th c.BC, (National Archaeological Museum, inv.no n9047. 1. Bezel of signet ring (back side) from Perati, Attica, 12th c.BC, (National Archaeological Museum, inv.no II6211. Both bezel and hoop are massive. The bezel is cast and hammered oval with an annular hoop soldered to the edges at the back of the bezel, in a typical manner of the period, as seen for example in bezels and signet rings from the site of Perati, Attica and the Tiryns Hoard exhibited in the Mycenaean Gallery of the NAM. The back of the bezel is slightly hollow in the middle (along the major axis), as a result of the smoothing process, in order to eliminate the joining lines. 4. Chips with striated tool marks at the upper edge of the bezel, revealing the core. 3. Successive lines of triangular incisions at the hoop of the ring. The low triangular section of the hoop is formed by an irregular middle rib. Six successive lines, each one composed of four triangular tool marks of various sizes are detected on half of the outer surface of the hoop. Caused by a punching tool (gouge) on its surface, remained on the surface, even after polishing, which is the last stage of the ancient goldsmith's work. Hollow scratches and incisions are traced on both sides of the bezel and the hoop, identical to those left from the ancient tools on the majority of the Mycenaean signet rings and their handling throughout their existence. Superficial cracks, as manufacturing defects, 8. Reddish and brown copper corrosion compounds at the joining of the hoop with the back side of the bezel. 6. Reddish and brown copper corrosion compounds on the upper part of the main side of the bezel. 7. Reddish and brown copper corrosion compounds in incision of the sphinx on the left. Manufacturing defect (crack). 5. Soil sediments in incisions at the body of the sphinx on the right. The condition of the ring is fairly good. Traces of soil sediments are detected in the incisions of the sphinx on the right (mainly at the legs, the body and the left wing), reddish and brown copper corrosion compounds are present in the incisions of both sphinxes and the joining of the hoop with the bezel on the rear side of the ring. 77. Too/ marks at the outer surface of the hoop.10. The narrow side of the hoop. Burr, cracks (manufacturing defect) and striations from rough polishing. mm , ^, 9. Scratches on the hack side of the bezel. r~ are present close to the edge of the main surface of the bezel and at the outer surface of the hoop. On the rear side, close to one narrow edge of the bezel, modern dense scratches from a sharp tool are detected, indicating a probable attempt for gold verification. Neither the bezel nor the hoop are adequately smoothened and as a consequence, the outlines of the gold plate are in parts irregular, confirming the archaeological evidence we have at our disposal, about the production of a peripheral workshop of the 12th cent. BC. Respectfully, Eleni KonstantinidiMaria Kontaki Overall, the impression acquired by the thorough study of the signet ring, with the dimensions, weight, style, and technical details (soldering of the hoop to the bezel, ancient patina, deposits, corrosion products and tool marks on the surface) strongly point to the identification of the signet ring held at the Medelhavsmuseet with the one stolen by the Museum of Rhodes during the Italian Occupation years. Concluding our report, we would like to thank our Embassy in Sweden for their warm hospitality and significant contribution to the case, as well as the zeal of all parties involved, the Director, the Collections Manager and the Curator of the Mediterranean Museum, the Nobel Foundation and the National Heritage Board, and stress out that the happy ending of this significant case for our national heritage, is the result of a unique conjuncture of devoted people and their perfect cooperation, of which we are proud to have been part, as also of the long and tedious research on behalf of the Directorate.
