Fig. 1 - Puttu de Inza nuraghe (by TARAMELLI 1919, fig. 31, pages 77 - 78).

Fig. 2 - Bronze brooch found near the Puttu de Inza nuraghe (by TARAMELLI 1919, fig. 34a, pages 83 - 84).
This is a multi-function ornamental item that could be used as a weapon, an ornament to fasten clothing or a hairpin.
The finding, which was fused, has a rectangular section stem. The sub-cylindrical pinhead has a neck decorated by three rings.
From a chronological point of view, based on the comparison with similar examples coming from other nuragic contexts on the island (figs 3, 4), it dates to the 12th-9th century B.C.
