1st-2nd century AD. A gold finger ring with ellipsoid cell to the bezel, inset onyx gemstone with intaglio figure of Mercury in travelling cloak (sagum) holding out his coin-purse (marsupium"). Cf.

c.13th century AD. A most unusual two-piece silver double personal seal matrix, the body of circular form with hexagonal handle and tiered collar with petal moulding at the base, one petal bearing an orientation mark in the form of a cross pattee, with a second such mark in the form of four pellets set opposite; the perimeter bears the legend '+ S' ThOME * DE * RO[ ]' for the seal of Thomas of Ro[ ]; the inner part showing a circular cell that would have received an intaglio gemstone linked to a shaft passing though the body to allow the central stone to be used either in combination with the inscribed border or separately; the second orientation mark would have been used when impressing the central intaglio alone. 8.85 grams, 22mm (1"). Found whilst searching with a metal detector near Copmanthorpe, close to York, UK, in September 2020, and disclaimed as Treasure under Treasure reference no.2020T10091; accompanied by a copy of the Portable Antiquities Scheme (PAS) report number YORYM-2006DE and the report for HM Coroner. Seals belonging to important personages often provided for their owner to make use of a full seal inscribed with their name paired with a smaller 'secret' seal of simpler form. This particular seal, which allows the owner to adopt either full or secret seal through the same matrix, is extremely unusual and creating the mechanism would have required skills beyond those normally seen used by ordinary seal cutters. The complex mechanism comprised a central shaft passing through the length of the body which is keyed to ensure the orientation between body and intaglio cell remains constant and the two orientation marks of a 'cross' and 'four pellets' allowed the owner to be sure that, when impressed into wax, the design would be correctly positioned for whichever version he desired. A wire spring kept the central element snugly in place until the shaft was pressed down. The seal is secular in type and the name of the owner is complete and reads 'ThOME' for Thomas and continues with the letters 'DE' signifying 'of' and followed by the letters 'RO' being the first two letters of the place name where Thomas was born or resided; from the space available, it is likely that there were originally four or five letters to the name of the place. The matrix was found near Copmanthorpe, Yorkshire. Copmanthorpe, situated a few miles to the south-west of the city of York, is a settlement listed in the Domesday Survey of William I. The place name could be taken from a city, town, settlement or manor and there is no obvious candidate in proximity to the place of finding; indeed place names in England beginning 'RO' are not common, with Rochester (often abbreviated to ROFI or similar in the Medieval period), Kent perhaps being a strong candidate, as the seal is obviously a very costly item that could only have belonged to a wealthy personage and Rochester was an important city that would have artisans capable of its manufacture and suitable as a home to a wealthy and important person. Fair condition, some loss. Extremely rare mechanical type.

1st century AD. A red jasper gemstone with a gold mount, depicting the bust of goddess Athena Parthenos (Greek Minerva), wearing the Pseudo-Attic three-crested helmet of Athena Promachos, aegis upon her breast. See Zwierlein-Diehl, Antike Gemmen und ihr Nachleben, Bonn, 2007, pp.408ff., fig.436. 2.07 grams, 23mm (1"). Property of a gentleman from Vienna; from his private collection; previously acquired in Munich, Germany, between 1992 and 1996; this lot has been checked against the Interpol Database of stolen works of art and is accompanied by AIAD certificate number no.10906-179190. The imagery on the gemstone is based on a famous model, which the gem-cutter Aspasios created in the 3rd quarter of the 1st century BC. It shows the bust of Athena Parthenos of Phidias made in red jasper and signed by Aspasios, today in the National Museum in Rome. The gem-cutter of our gem omitted certain details, such as the lance, and depicted the bust the other way round. [No Reserve] Very fine condition.
