## What you would see

The object is shown centered against a flat, medium-gray background, viewed from directly above as if lying on its back. It has an elongated T-shape, with a small cross formed at the top. The body is made of bronze with an uneven, mottled patina ranging from mossy green and brownish-green to dark charcoal gray, its surface rough, pitted and corroded with age. At the top are three prominent onion-shaped knobs, one on the central bow and one at each end of the short transverse bar. The central bow is thick, arched and raised, with a delicate incised line resembling a braid or herringbone running along its crest. Below the bow, the long flat foot extends straight downward, noticeably longer than the bow itself, with slightly notched edges. Its face is decorated with repeating concentric circles, arranged in groups of four at the top and bottom, and a central vertical band with diagonal hatching. Near the lower end a small round hole pierces the metal. Even overhead lighting emphasizes the texture, casting soft shadows that highlight the raised ornament against the dulled, oxidized metal.

## How to look at it

Start with the overall T-shape and the three bulbous knobs, then follow your eye down the arched bow to the flat, patterned foot. Notice how the tiny concentric circles and the hatched central spine transform a practical fastener into a carefully ornamented object.

## Context

According to data from the Cleveland Museum of Art, this is a cross-bow fibula dated to 1–200 CE, attributed to Roman culture in Italy and made of bronze. The maker is unknown, as is typical for such utilitarian items. Fibulae were brooches used to fasten clothing, functioning like modern safety pins, and their typology changed considerably throughout the Roman period. This crossbow type, with terminal knobs and a long decorated foot, was widespread in the early Imperial era. The work is housed in the Greek and Roman Art department. The source provides no further description, so its precise findspot and original owner are not recorded.

## Curious detail

Roman fibulae were more than jewelry: they worked as clothing clasps for togas and cloaks, and because their designs evolved quickly, archaeologists today use fibula types as reliable dating markers for Roman sites.

## Questions

- What does the green patina and worn surface suggest about the life of this object after it was lost?
- How does knowing it was an everyday dress fastener change the way you see its decoration?
- What balance do you notice between function and ornament in its design?
