The restoration of this leve! would regain the originaI superb spaciousness of the mosque, and therefore ought to be taken into consideration. Finally let us mèntion the results of the excavation in the so-called Muzaffarid extension to the North. A construction of considerable inter-
ed by a column decorated in stucco which had already been identified by Galdieri and dated by him to the Sassanian period, leads us to ,think that the courtyard of the mosque most probably corresponds to a formerly-existing open &pace. In order to verify this hypothesis, as welJ 'as to determine the presumed subsequent expansions of the mosque, the research campaign for 1974 has as its object the cutting of a wide trench across the width of the courtyard. The excavation in the area of the sanctuary (190) has ascertained that the column of Sassanian type is certainly in positionand that its base rests directly on the foundation plinth (fig. 5). Thus two factors of considerable interest have come lo light: A) neither the base nor the foundation of the supposed column of the Arab network, corresponding to I 1 in Galdieri's scheme, was found, but in its pIace there is a huge fall of unbaked bricks; B) a wall was discovered which is orientated obliquely and belongs to a fairly important building with polychrame stucco decorations which are comparable with the stuccoes of the Friday Mosque of Nayin and with those discovered recently in the SIraf mosque (cf. D.E. WHITEHOUSE in Iran, VI, 1968, pI. VIII b) (fig. 6). The £Ioor-line of this wail is much higher than the base of the "Sassanian" column, which, hovever, could have been "utilized" in the later construction. Tbe wall with polychrome stucco decoration was intersected at its southern end by the foundations of the Seljuq sanctuary. These factors lay open to debate the theory that the Abbasid mosque of the ,£irst third of the 10th century extended as far as the present southern boundary. This was perhaps not definitely included in the mosque until the Seljuq periodo Tbe excavation in the sanctuary area has also yielded up fragments of mud plaster with painted decoration, unfortunate!y in rather bad condition. The decorations consist of vegetaI motifs and Kufic inscriptions painted in blue, various shades of red, black, green, and gold. These rragments, judging from the position in which they were found, probably belong to the 'pictorial decoration of the mosque before the interventions at the time of Malek Sah. We are also of the opinion ,that some interesting stucco fragments executed ina vigorous and sensitive style, which come from the "sanctuary" area ,as well, may likewise belong to the pre-Seljuq mosque (figs. 8-10). The excavation in the zone southwest of the prayer hall has enabled us to confirm that the originaI floor leve! in this area was ,at least 50 cm. below the present one, that is, about the same as the Seljuq leve! in the sanctuary (fig. 7).

a small
palace with centraI courtyard and iwan. The decoration attributable to this building presents a combination of remarkable features which in some ways are reminiscent of Sassanianart, while other technical aspects and the choice of decorative motifs c10sely recall proto-Islamicart. Our present hypothesis is that it must bea protoIslamic monument which paves the way for the subsequent development of the Buyid architecture, as is known to us, for example, in the Gorgir portaI. Chronologically the building is without doubt earlier than the Abbasid mosque, on the evidence of the walls of the precinct in mud brick (which up till now we have good reason to believe belong to the first third of the 10th century) since some of these walls have been incorporated in the large perimeter wall which marks the northern boundary of the mosque. Shahr-i Sokhta. The Italian Archaeological Mission conducted a research campaign in Sistan in the period October-December 1973 under the leadership of Prof. Umbert:o Scerrato. In the absence of Dr Maurizio Tosi who was detained by other engagements in Italy, Dr Marcello Piperno was appointed acting Field Director in charge of the excavation at Shahr-i Sokhta, with the archaeologist Dr Raffaele Biscione and the anthropologist Praf. Edoardo Pardini, as wellas Mr Sebastiano Tusa, student; Mr Gabriele Graziani, assist:ant; Mr Guido Regoli, restorer; Miss Patrizia Zolese, photographer; the architect Dr Luca Mariani, topographer and draughtsman. The Iranian Archaelogical Service offered, as usual, its valuable aid. In this campaign its representative was Dr Ahmid KhatibShahidi who took an active part in the excavation and gave his efficient collaboration on every occasiono During his sojourn in Sistan with the Mission, Praf. Scenato, together with Mr Graziani and Dr Khatib-Shahidi, conducted surveysat Qal'ah-i Sam, Qal'ah-i Tepe and Dahan-i Ghulaman in order to control certain points and to programme ,additional research in view of the final publication of the excavations which he has carried out there in previous years. The main centre of actìvity in this campaign at Shahr-i Sokhta was the area of the necropolis, where the excavation of the trenches begun in the 1972 campaign was completed, that is the extensiveexcavations in thearea IR and in the squar;:
