Splendid disc from the terramara of Castione Marchesi (about 1650-1150 BC), obtained from the deer's antlers.

The entire surface of the disc is carefully engraved with patterns of concentric lines, wavy lines alternating with small dots and lines formed by dots. Eight small circular and shallow recesses probably contained amber plaques, while another plaque could perhaps have been inserted in the centre. It is a unique object among the thousands of horn artefacts found in the terramare and, over time, has given rise to various interpretations

Archaeologists have linked some discs in gold foil found in very distant areas to the solar cult practiced in the Bronze Age. A small bronze group was found in Denmark, consisting of a chariot pulled by a horse and surmounted by a disc covered with gold foil: it dates back to the mid-15th century BC and is considered the first representation of the sun's journey through the vault celestial well known in classical mythology.

Other embossed decorated gold foil discs have been found in the terramaricola area and in other localities, including an important Bronze Age village in southern Italy; it is thought that these plates were applied to perishable supports (perhaps wood) and used in ritual practices.

Although made of a less valuable material than gold, it is possible that the horn disk of Castione Marchesi also had a similar function; the possible presence of amber (precious material with a color between yellow and gold) could further confirm this interpretation.
