well as in the metallurgical traditions. The plan of the building is a series of square and rectangular rooms, peripheral corridors, straight-sided doors with well-marked sills and two staircases, leading to an upper terrace-store, whose steps have the edges strengthened by t,imbet frames: ,a technique destined to last for long in the architecture of Iran. The end of the palace was certainlya violent one as the whole of the building shows evident traces of an extensive fire: collapsed beams, wall-plasters and £1oorsfuHy burnt, broken jars still in situ and a burnt human skeleton lying on the floor of the most northern, isolated room. The body fell among Period IV buff pottery, and the right hand was still holding a stone pestle. The Palace shows only a single building phase, because direct1y underneath the burnt floor level, the setting of the foundatiom cut the deposits of Period II, characterized by buff painted ware.
The archaeological excavations and restorations of IsMEO in Asia, of which a brief survey is given below, were carried out thanks to thecooperation of and a gran t from the Consiglio Nazionale delle Ricerche (CNR). The Italian Archaeological Mission to Iran has been operating of the months of SeptemberNovember 1969 under the direction of Dr M. Tosi, with the following staff: Mrs F. Bonardi, photographer; Mr G. Graziani, assistant; Mr G. Regoli, restorer; Dr V. Labianca, architect and draftsmani Mr M. Piperno and Mr M. Bonelli, students. The Iranian Archaeological Service was ,represented by Mr A. Darbani. The researches on the earliest cultures of SIstan have been continued this year, by enlarging excavations on the main Bronze Age site of the .region, Shahr-i Sokhta (figs. 1-3), on an area of over 1200 square metres. The main aims this year were to explorea wider surface of the dense inhabitation area (Periods I-IIl), to study in alI details one more building beside the «House of Staircases », conduded in the past season (Period Il-IlI), to increase documentation on the Late Chalcolithic layers (Period I), and to start excavations on the highest point of the mound.
The discovery of a fourth period of occupation, to which can be related the « Burnt Palace », completes the cultural sequence of Shahr-i Sokhta. It can now be divided in the following way: Period I: Late Chalcolithic, with bichrome buff and red/b1ack on gray ware, painted with geometric designs. The generaI picture is very dose to thar of the Geoksjur Culture (Namazga III of the South Turkmenian Sequence). Among the finds, three sealings of cylindrical seals of a type apparently very dose to late Uruk or Jemdet Nasr. Periods II and IlI: Early and Middle Bronze Age: they show a slow but continuous development of the earlier Chalcolithic models into highly standardized pottery types. Bichrome wares disappear and th;: pottery classes are limited to black on buff and black on gray wares, with. the exception of a polychrome pottery, usually limited toa relatively small number of specimens. Stamp-seals of a compartmented type are widely employed, and frequently occur: day anthropomorphic and theriomorphic figurines, various types of metal, tlmber and stone tools and a wonderful bronze figurine, 29 cm. high, representing a woman carrying a jar on her head, with striking Mesopotamian features (figs. 4, 5). It was discovered on the surface, but is most likely to relate to these periods, which in terms of absolute chronology could mean the second half of the 3rd millennium. This period has connections with Namazga IV and Bampiir I.IV. Period IV: Late Bronze' Age. As already stated, this period sees the end of the painted tradition, the introduction of the fast wheel, new types of stamp seals and anthropomorphic figurines and, apparently, a great increase. of architectural skill. On the basis of the pottery found in the destruction level (Level 4), we might associate this period with
With the 1ast aim we intended to uncover a main, well-preserved building, which could provide us with extensive information on the ,large-scale architecture. Our hypothesis turned out to be correct, as at the end of the season we had com. pletely isolateda building, extendingfor at least 500 square metres, with massive mud-brick walls, rising to a height of over 3 m. Three sides of the building's perimeter had unfortunately been washed ofI by erosion, but we were able to isolate the fourth one and thesouth-east corner. This large building represents a new period in the cultural sequence (Shahr-i Sokhta IV), completely undocu. mented in past campaigns. Period IV marks the introduction of the fast wheel in pottery manufacture; the pottery types are characterized by articulated shapes with straight corners, buff or brkk-red in colour, rarely painted, but frequently red-slipped or burnished in parallel lines; a much smaller percentage are of black-burnished grayware and buff jars decorated in Late Bampfu style, carrying padnted and moulded elements. Period IVappears to be datable to the first quarter of the 2nd millennium and the genera! evidence shows, notwithstanding the sharp changes, a rematkable cultural continuity in the pottery, as 544
