It follows that the terracotta sculptures characteristic of @ must be considered stratigraphically contemporary (Le. thrown in with the same filling material) with the sculptures in yellowish unbaked day and the pottery with impressed

A serious and prolonged drought prevented any further progress in Seistan in 1971. The state of preservation of earlier work, and of the monuments, was checked by Dr Maurizio Tosi in a brief visit from 17th to 20th September. Dr Raffaele Bisdone, member of the Mission, stayed in Iran from 28th July until 10th November 1971, and took part in: the fourth season at Tepe Yahya (Kerman), directed by Prof. C.C. LambergKarlovsky for the Peabody Museum of Harvard University; the second season at the Parthian dty of Qumis, near Damghan, directed by Professor J. Hansman and DrD. Stronach for the British Institute of Persian Studies; and in the survey of western Luristan conducted by Professors L. Van den Berghe and W. Le Rouge for the Belgian Archaeological Mission. Between September 20th and 22nd, Dr Tosi and Dr Bisdone paida brief visit to the upper valley of the Atrak, between Quchan and Bojnurd (Khorasan), in order to investigate the position and density of the ruins along the south face of the Kopet Dagh. Given that new absolute dating techniques have emerged in 1he wake of the Radiocarbon method, it is logical to apply as many of them as possible to the as yet unresolved problem of the chronology of the settlements in eastern Iran

Soundings a.Iong the west flank of the hill have barely begun; a long trench has been opened. So far, a stupa (no. 64) has been found there; it is made of small schist slabs, very much like stupa no. 11 (at the north-east corner of the pradakfilJiipatha of the Great Stupa), and is under layer @. This is the first dear stratigraphical connection between the small schist slabs and the sculpture that precedes the last phase. The long trench mentioned above has revealed part of a building constructed in thin courses of pabsa (pisĂŠ) with light blue plaster, red on the surface, of the same type as that found in fragments in @. An arrow-slit is satisfactorily preserved in the exposed portion of the building. The upper part of the fallen chapel (vihara) no. 56, next door, to the east, to chapel no. 37, was also removed In addition, the collection of unbaked-clay sculpture fragments on the floor of chapel no. 37 was completed; these fragments made it possible to put tagether most af a splendid life-size standing image of Bodhisattva (Inv. no. TS. 1272), still polychrome over much of its surface (cf. EW, XX, 1970, p. 509, fig. 6). Also in chapel no. 37, the Mission's restorer!> undertook the considerable task of cleaning and consolidating (with metal frames, and chemically) the remains of the decoration at the centre (fig. 2): the group of two niigas emerging from the waters beside three lotus stems growing from a single calyx to support the centraI flower on which the Buddha sits, together with the two flowers at the sides, which probably served as pedestals for two Bodhisattvas (one of this pair was dea,rly that mentioned above).

reference to the site of Shahr-i Sokhta in Seistan, where the Italian Archaeological Mission has been involved since 1967. A certain quantity of charcoal is currently being examined at the Institute of Geochemistry in the University of Rome; and a first selection from Tapa Rud-i Biyaban 2 (Shahr-i Sokhta IlI) has been treated and dated in the Tehran University Nuclear Center. In 1970, the partidpation in our campaign (cf. EW, XX, 1970, p. 509) of five Japanese geologists and physidsts from the Universities of Osaka and Kyoto (leader, Prof. N. Kawai) led to the acquisition of the first chronological information by residual palaeomagnetism on hearths, ovens and kilns from Shahr-i Sokhta, Tapa Rud-i Biyaban 2 and Dahan-i Ghulaman, and by U-238 Fission tracks. The latter method was used on numerous fragments of pottery from all the levels in the proto-historic sequence. The first results, somewhat different from those obtained by C-14, are assembled in the accompanying Table.
Regarding the terracotta production typical of phase @ of the filI, many pieces are worthy of note for their beauty and their exceptional iconographicimportance (figs. 3, 4). It must suffice here to record that the fragment ofa male head, with moustache and a 'ribbon knotted under the chin, noted in EW, XIX, 1969, p. 546, fig. 10), is now complete as regards the upper paĂŒt, including the forehead and a conical cap (fig. 3); it dosely resembles the head of the Ku~iiJ;laprince from Dal'verzin Tepe (Uzbekistan). Finally, the walls of the vihiiras (chapels) along the south sideare being restored. In particiIlar, chapel no. 23 (cf. EW, XIX, 1969, p. 545, fig. ,6) can nowbe considered safe from
