Polished hatchet in green stone (from Puttu de Inza nuraghe in Bonorva)
Among the materials recovered at the Puttu de Inza nuraghe complex (fig. 1), located on the plain of Santa Lucia, there was also a rectangular green stone metamorphic hatchet, with a straight cut, 9 cm (fig. 2).
This is a rather common tool, belonging to the stone industry category in polished stone, found in prehistoric settlements (figs. 3, 4, 5, 6).
The hatchet production process involved several stages:
a) Search, extraction of raw material blocks or use of suitable local stones;
b) Roughing and shaping of item by direct shaving using a striker, usually a hard, strong stone;
c) Shaping the item by bush-hammering;
d) Finishing the item by polishing/shining.
According to the archaeologist A. Taramelli, who was the first to study the monument at the beginning of the twentieth century, it comes from the time when the nuraghe was built.
