Ca. 100-300 AD.A bronze openwork gammadion or tetra-gammadion brooch with a catchplate on the reverse, composed of four capitalised ? (gamma). Brooches were an important element of Roman dress, used to fasten clothing but they also served as dress accessories in their own right. Thousands of different types and subtypes of Roman brooches are attested, and they seem to have played an important role in Roman people's self-expression. This item may have belonged to a devotee of Jupiter, probably a soldier, as he was a particularly important deity among Roman military communities.
