15th century AD. A large bronze circular seal matrix: incuse and reverse armorial bearings of Antoine of Burgundy; central design comprising a bird, possibly an owl, standing on a helmet on a heraldic shield, flanked by rearing winged griffins among other banners, all encircled within a border; legend inscription in blackletter script reading 'S' anthoine bastart de bourgomgue conte de la nothe'(?), punctuated by small crosses or lis motifs and enclosed by circular border; integral raised rib and 'lug' through diameter on reverse; supplied with an impression. 55 grams, 52mm (2"). Property of an Essex collector; acquired by purchase Didcot, 1996; accompanied by report 714 by the Academy of Saint Gabriel, and file of associated information. The seal was probably part of the spoils of the Burgundian wars in 1476/1477. Antoine of Burgundy, also known to his contemporaries as 'the Large Bastard' was born in 1421 to Philip III, Duke of Burgundy, and one of his mistresses, Jeanne de Presle. Antoine died in 1504. He bore at least two of his father's arms, sometimes adding a 'bendlet sinister argent overall' or by displaying his father's arms upon a broad bend, as in the case of his seal matrix.
