In 2020, a surface survey using metal detectors was conducted at site 7 at Ryczywół, Kozienice County. The site is located on the north-eastern edge of a promontory of a fluvial terrace cutting into the Middle Vistula Valley, about 1.5 km southeast of the present-day confluence of the rivers Radomka and Vistula (Fig. 1). It is part of a larger Przeworsk Culture settlement complex. During the survey, 10 fragments of pottery from the Roman Period or the Migration Period (including vessels made with the help of a potter’s wheel), a denarius of Marcus Aurelius and two copper-alloy fibulae were found at the site.

The first of the two fibulae is a small (29 mm long) knee-shaped brooch with a small crest on the head, similar to Almgren type 132, pre-served without a spring and pin (Fig. 2:1). Brooches of this type vary in size, form and material used in their manufacture. Iron specimens come mainly from the area of the Przeworsk and Luboszyce Cultures, while pieces made of copper or silver alloy are known from the area of the Wielbark Culture. Stylistically, the brooch in question most resembles Wielbark Culture fibulae of Almgren type 132, although close references are also found in the Upper Elbe region and in the Morava River basin, mainly among brooches of variant BGKF D distinguished by Eduard Droberjar. The lack of direct analogies and the fact that the discussed fibula is a stray find do not allow its more precise dating. Nevertheless, taking into account its stylistic features and referring to the general findings regarding this artefact group, the brooch can be dated to phase B2/C1−C1a of the Roman Period.

The second fibula (43 mm long) is likewise damaged (Fig. 2:2). It has a full catch-plate and a spherical knob on the head, which allows it to be identified as one of the so-called Bügelknopffibeln, known primarily from the West Germanic cultural circle. They are also encountered in the area of the Dębczyno group, the Wielbark and Chernyakhov Cultures, with isolated specimens found in the Przeworsk Culture territory. It has close stylistic analogies among finds from the West Germanic cultural circle, but its closest parallels can be identified among materials associated with the Goth cultural circle in the broad sense. It should be dated within the range adopted for Bügelknopffibeln, i.e., from phase C3 of the Roman Period to phase D1 of the Migration Period.

The two brooches are evidence of long-distance contacts maintained by the population inhabiting the area of present-day Ryczywół in the Roman Period and at the beginning of the Migration Period.
