Independant researcher: particularly interested in questions relative to the nuragic civilization and the Sardinian and western megalithism, presently studying existing correlation between some menhir complexes and the paleo-astronomy through the utilization of informatic procedures which I have expressly set up.

Governing analyst instructor in the Data Processing Center of Sardinia's Regional Authority Board;

Honorary Inspector of Archeology for the Archeological Authority of the provinces of Cagliari and Oristano, for the Boroughs of Muravera and Villaputzu, situated on the south-east coast of Sardinia;

I carried out the census of the existing archeological muments in the Boroughs of Castiadas, Muravera and Villaputzu, which are made up of hundreds of monuments (protonuraghi, pseudonuraghi, nuraghi, nuragic forts, hypogean and 'passage-way' tombs, a few (21) menhir complexes consisting of dozens of elements fixed in the ground in the original orthoptic positions in particular, in the locality of Cuili Piras and Nuraghe Scalas in the Muravera territory, I recently discovered two menhir complexes (the first composed of 46 elements and the second of 42 elements), positioned in such a way as to form Cromlechs (prehistoris circie of upright stones) similar to the II Phase of Stonehenge.

  Area centrale del complesso megalitico di Cuili Piras: il primo mehirs della serie in primo piano, in allineamento con il secondo della serie successiva indica il nord astronomico.

 Complesso megalitico di Nuraghe Scalas: i menhir antropomorfi, impiantati intenzionalmente inclinati ed in correlazione con l' area centrale.

The structural survey was carried out and the azimuths originated by the alignment were calculated and this data, stored in a Data Base File and correlated with another DBF containing all the azimuths achieved by the rising and the setting of the Sun and of the Moon calculated for the area by the Astronomer Angelo Poma, the Director of the Astronomical Observatory at Poggio dei Pini in Capoterra, Cagliari.

The results were astonishing: all the astronomically significant elements of the Solar Calendar are perfectly identified and, simultaneously it is possible to correlate the lunations.

Therefore, it can be supposed that these megalithic complexes function as astronomical instruments in order to constitute a primitive but precise calendar and to presumably forecast eclipses of the Sun and of the Moon, similar to Stonehenge.

With the purpose of evaluating the accuracy of my conjectures regarding these megalithic complexes, I would like to correspond and exchange information, photographs, slides, planimetries and computer applied procedures to use on P.C. with other researchers in this field i'm sure Is carrying out similar studies to mine.
