Shahr-i Sokhta
The southern extension of the phase 3 building happens to be supported by older structures, probably from phase 5.
The eighth excavation campaign at Shahr-i Sokhta was carried out under the auspices of IsMEO and of the Ligabue Foundation in Venice from 2nd October to 5th December 1976. The mission was composed of Dr Marcello Pipemo and Dr Sandro Salvatori who, at different stages, led the missioni Mr M. Ismail Bayiini, who represented the Iranian Centre for Archaeological Research; Mr Massimo Vidale, ceramologist; ProÂŁ. Edoardo Pardini, anthropologist. The primary aims of the present campaign were to continue the excavation of the graveyard and to extend the dig in the S and N sectors which was begun last year for the purpose of unearthing a large building found by analysis of aerial photos and by direct prospecting on the ground. The settlement. Excavation activity continued with the parti al deepening of the 50 x 20 m. trench begun last year. It was thus possible to detect two successive building phases of the foundation structures discovered during the last year's campaign (squares SCK, SCL, SCM, SCN, SCP, SCQ, SCR, SCS). The whole area appears to have undergone a process of erosion which has wom away the structures of this building in practically every part, even below fIoor level, so that almost everywhere, we find scattered over the surface materials from phase 5 (Period II), Le. older than the structures of the large building itself. The first building phase of this construction, which has a square ground-plan and well-distributed intemal spaces, can be assigned to phase 4 (Period 111). The building seems to have been later levelled to the ground and a second construction built on top of it. The latter coincided with the first except for very slight differences in orientation and was also extended on the south side by means of a construction composed of small regular rooms, perhaps used as stores (fig. 16). This second construction phase seems to date back to phase 3, Period 111, as here it was possible to discover fIoor levels covered with potsherds that could be assigned to phase 3 (a phase that is known above all through the material from Tepe Rud-i Biyaban 2, a pottery production centre tested in 1972 by Dr M. Tosi, the materials of which are now being studied systematically by Mr M. Vidale). Typical of this phase are vase forms such as plates, bottles, small truncate-conical thin-walled bowls made on the wheel and a decorative repertory consisting of no more than a dozen painted motifs, usually extremely repetitive.
Less extensive but more interesting from the structural standpoint is the originaI phase 4 construction, probably having a square ground-plan (the east side has not yet been explored) whose foundations are unfortunately alI that has been preserved. The perimeter walls are up to 1.80 m. thick, an unusual size for Shahr-i Sokhta archi tecture as we know it today. It was also possible to unearth and follow in critical points, such as comers and wall junctions, the foundation trench, which varied in depth from 1.50 m. to 1.80 m. and to darify the construction details of the comers of the building. In the southwestem corner it was possible to see how the foundation trench widens towards the inside and also discem a later organic filling after the masonry work had been completed. This particular method was revealed by an excavation of the section CDXXII and of the area outside the southwestem corner of the building. The foundation trench cuts through the preceding levels down to the phase 7 ones (beginning of Period II) as was found in square SCS to the north and in square SCK to the south. At other places in the excavation structural levels ranging from phase 3 to phase 7 (Periods 111 and II) have been unearthed. This is the case for squares SCP and SCK where at least four successive structural levels with architectural elements and fIoor levels have been found, even though virgin soil has not been reached. Of some significance is the discovery in the southeast portion of SCP at a depth of 80 cm. below ground level of a water pipe consisting of ceramic tubes, each 1 m. long, fitting into one another and buried in a small canal the walls of which had been lined with a day mortar mixed with straw (kĂ hgel) (fig. 17). This type of piping had already been found at Shahr-i Sokhta; a few connecting tubes were found 15 m. south of SCP in a test trench dug by Dr M. Pipemo in 1969. The pipes found this year are probably part of a large main joining the one found in 1969. To the north only square SCS has been completely excavated. Rere a few structural phases have been unearthed ranging from phase 5 to phase 8 (end of Period I) (fig. 18) although it is not actually possible to distinguish any consistent architectural plano In fact, the building process in this area seems to have taken pIace through successive demolitions and reconstructions, unlike other excavation areas where the filling technique has made it easier to identify the structures. The most interesting result in this sector is the discovery in a phase 5 level
