A HYPOTHESIS ON A BUILDING TECHNIQUE TO BUILD THE NURAGIC THOLOI.
The nuraghe is the main type of ancient megalithic edifice found in Sardinia, developed during the Nuragic Age between 1900 and 730 B.C.
There are many kind of nuraghe:
PROTONURAGHE:
Protonuraghe are considered to be the most archaic type; they differ somewhat from the "classical" (tholos vaulted) Nuraghes in their stockier look.
Protonuraghes generally follow an irregular plan and lack the large circular room present in presumed later forms; instead, they are laid out along
one or more corridors or long rooms. Although lacking the central circular room, they are sometimes similar sizes as later nuraghe.
MIXED NURAGHE:
This type is distinguished by the restorations made in later times, supposedly due to a change of the Protonuraghes design, or for other needs.
A "TANCADU" NURAGHE: (Sardinian term for courtyard) represents the evolution of the single tower Nuraghe; another circular building was later added to the main tower, with two enclosing curtain walls connecting the two. A courtyard was present within the structure, sometimes provided with a well.
POLYLOBED NURAGHE:
Also called Nuragic royal palaces, the polylobed Nuraghes are the least frequent typology.
Very elaborate and often designed in a unified manner, they look like veritable fortresses with several towers linked by high ramparts,
whose function was to offer more useful space and perhaps to reinforce the central tower. These "Megalithic castles" were surrounded by additional walls, sometimes also provided with towers (the so-called bulwark).
SINGLE TOWER NURAGHE:
This is considered to be the predominant type of Nuraghe, and it represents the most diffused typology. The single tower, of a truncated conical shape, accommodates within itself one or more superimposed chambers, covered by a tholos-shaped chamber. The access, generally located at the ground level, leads into a passageway that leads, in the front, into the central chamber and in one side (usually the left) in the helical staircase, built inside the wall mass,that lead to the terrace or to the upper-floor chamber.
This short 3d animation tells a constructive hypothesis about the nuraghes. One hypothesis tells of the nuragic building site built thanks to large wooden scaffolding anchored to the nuraghe through strange holes too small to be windows called pontai holes.
For the transport of large blocks of stone it is thought that wagons pulled by large oxen and strong men were used, and also by rolling on wooden logs.
Without thinking of absurd magic, it is evident that every age has its own technology. This was also the case for the Bronze Age.
Questa breve animazione 3d racconta un'ipotesi costruttiva sui nuraghi. Un'ipotesi racconta del cantiere nuragico costruito grazie a grandi lignei
impalcature ancorate al nuraghe tramite strani fori troppo piccoli per essere finestre detti fori pontai. Per il trasporto di grossi blocchi di pietra si pensa che venissero utilizzati carri trainati da grossi buoi e uomini robusti, ed anche facendo rotolare su tronchi di legno.Senza pensare a magie assurde, è evidente che ogni epoca ha la sua tecnologia. Così è stato anche per l'età del bronzo.
