In Lunigiana up until the present day, approximately 80 statues have been found. A.C.Ambrosi divided them into three groups (A, B and C), in relation to their form and structure.
Group A, comprises of the Stele Statues characterized by their head in the shape of a semicircle which is not separated from their body. The arms and fingers are represented with a series of parallel lines and the face, in the form of a “U”, represents the eyes. On certain statues two hollowed out circles, which appear on the sides of the face, represent ears or earings.
In Group A the female figures are recognisable by their breasts and the men are indentifiable by the dagger placed under their hands.
Group B, contains the most statues. There is a clear evolution from the previous group, shown through the greater definition of anatomical details and a clear distinction between the head and the body. The head, in a semicircular arch, has a wide side-ways expansion and for this reason its shape is seen to be similar to the italian policeman's hat. It is attached to the body by a cone-shaped neck.
The face is U-shaped, like the statues of Group A, or in a strip-like circle and in relief from the head. From the tip of the “U” is a vertical appendix which arrives in the centre of the head and represents the nose.
The statues from this group also represent the collar bone, and the arms and the fingers are represented in a more natural way compared to the Stele Statues from the previous group.
The female Stele Statues are identified (aidentifaid) by their breasts and sometimes by a jewel worn in the Copper Age, the effect of which is achieved (acivd) by a series of parallel carvings on the neck. There are also representations of necklaces formed by three semicircular carvings, or by a semicircular relief around the neck.
The male Stele carry a dagger which could be associated with an axe. In certain cases the dagger seems to be inserted into a rectangular sheath (shith).
Other statues from this group are but fragments, often there is only a head which is impossible to associate with female or with male figures.
Group C, comprises of the most recent statues. These are identified by a more realistic representation of the human figure and both the front and back of the statue have been sculpted creating a three dimentional effect.
Only male figures are represented in this group, with a rounded head distinct from the body by a rather large neck. The face is enriched with precise anatomical details; in the case of Filetto II, the legs and feet are also represented.
The statues of Zignago, Campoli and Filetto I are re-workings of examples belonging to the two previous groups.
In the majority of cases these Stele Statues have short ankle-tip swords and square blades with long handles. In some cases the swords which are present on the hip, hang from a belt.The male statues also sometimes carry a pair of javelins or a spear.
On the statues, a belt is always present and in certain cases a triangular loincloth is represented. On the Stele Statues of Lerici a shield and helmet are present, which also seem to appear on the Stele Statue of Reusa.
The Stele Statues of Zignago, Filetto II and Bigliolo are engraved with Etruscan inscriptions.
