A laminated and engraved bronze fibula dating to the 8th-7th centuries BC.
This object belongs to the type of hollow sucker fibulas, characterized by an arcuate structure and engraved decorations along the outer surface. The ornamental motif consists of bundles of crossed lines arranged in a herringbone pattern. At the center, laterally to the longitudinal band, are two concentric circles with a central dot. This type is documented in several archaeological contexts, with notable examples from Tivoli and Pratica di Mare (Civiltà del Lazio Primitivo, Rome 1976, plate XXXVI, C, cat. 64, 2A; plate LXXVIII, T. LXII, cat. 100). According to R. Peroni (BPI, LXXV, 1966, p. 175 ss.), fibulas of this type belong to the second phase of the First Iron Age, between 775 and 750-734 BC.
The fibula measures 5.2 cm in length, 3.2 cm in height, and 2.2 cm in width, similar to a common metal paperclip, and is in poor condition. The pin, clasp, and spring are missing, compromising the object's original function. However, the main structure and the engraved decoration are still clearly legible, allowing for clear identification of its type and chronological context.
On this webpage, a series of slides illustrate the step-by-step process of the 3D modeling of this historical artifact. The images show how the final 3D model, enriched with photographic data, was obtained by modeling point clouds with extreme precision in millimeter measurements. The virtual model has been prepared for 3D printing, allowing for the creation of a tactile replica of the artifact.
