A cast bronze artifact with a green patina, dating to the 6th century BC.
The object has a ring shape, with a lenticular cross-section, which gives it a thin and symmetrical profile. The bronze casting and light green patina indicate a long natural oxidation process, compatible with the referenced chronological period. The ring may have had a practical, decorative, or symbolic use, common in the metalworking crafts of the time. It measures 8.5 cm in length, comparable to the width of a palm, and is perfectly intact, with the original structure fully preserved. The light green patina, resulting from the natural alteration of bronze over time, does not compromise the legibility of the shape and craftsmanship of the object
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.
