A cast bronze monogram ring attributable to the Byzantine Empire, dating to the Middle Byzantine period (approximately 10th–12th century AD). The ring is formed with a flattened circular bezel engraved with a worn but discernible monogram design, composed of interlaced linear elements. Such monograms were commonly used in the Byzantine world to represent personal names, devotional formulas, or abbreviated invocations, and frequently appeared on rings worn as personal identifiers or seals. The hoop is thick and sturdy, with a slightly angular exterior profile and a smoothly worn interior, indicating long-term wear. The surface retains a dark, stable patina with areas of corrosion and mineral accretion consistent with age and burial conditions. The engraving shows appropriate wear, supporting genuine antiquity rather than later manufacture. Monogram rings of this type were widely used across Byzantine territories by civilians, officials, and members of the military, serving both decorative and symbolic purposes. Material: Bronze Condition: Good ancient condition; intact. Surface wear, patina, and corrosion consistent with age. No modern repairs or restorations observed. Decoration: Engraved monogram on bezel Culture: Byzantine Empire Dating: Circa 10th–12th century AD Provenance: From an old private collection
