The lithic cistas: function and use (funerary ritual)
During the fifth-fourth millennium B.C., at the same time as the custom of underground burials began, the custom of burying the dead inside a stone cista spread throughout Spain, France, Corsica and Sardinia.
This aspect of megalithic burial is documented in the necropolis of Li Muri, and dates to Sardinian Late Neolithic Culture (3400-3200 B.C.).
The cista, single or combined with other small necropolis, is generally formed by four blocks of stone placed side by side and buried; it can be underground compared with the ground level or visible on the surface, of rectangular, square or trapezoidal shape, without a protection structure or enclosed within a ring of stone slabs arranged with small and medium size rubble and a circular mound structure or with a ring of single stones, a double external wall circle or large vertical stone slabs (fig. 2).
The type of cover of the burial cistas of Li Muri is unknown, as they have always been found without any possible top slab.
The same situation was discovered in comparable monuments in southern Corsica, similar to those of Gallura, a fact which has led some to hypothesise the original existence of a wooden cover.
