The principal object of the campaign was to demolish the great baulk that had purposely been left unexcavated from the very beginning to provide a record of the stratigraphy of the site.* This earth was now required by the Restoration Department of the Greek Archaeological Service to secure and safeguard the mud brick walls that were destroyed in a great fire in Late Helladic IIIB towards the end of the 13th century BC. The intensity of the fire had served to preserve these walls in their original state, though off axis, and they are the most complete examples of their kind on any Mycenaean site. The second object of the excavation was to uncover the rest of the plan of the LH IIIB walls which in the western sector of the site are buried below the postdestruction walls of LH IIIB/IIIC. The second objective was only in part accomplished because of the remarkable and outstanding finds that were brought to light, mostly under the great baulk. The work of their recovery sIowed down the excavation considerably. At the east central end of the great baulk a small room, c. 2 m. x 2 m., was uncovered that was filled with a great variety of clay objects in considerable disarray (PL. xra; see plan, FIG. I,I). Outstanding among these were idols from 0.50 to 0.60 m. in height of a kind that had never been found on the Greek mainland before, although somewhat similar examples are known from Gazi in Crete [I]

The excavation of the School in 1968, as in 1967, was at Knossos. In addition, a new excavation under Dr A. C. Renfrew was sponsored at Photolivos in Thrace, and Dr P. Warren's excavation at Myrtos on the South coast of Crete was completed. Underwater operations at Elaphonisos in the S. Peloponnese led by Mr R. C. Jones were also sponsored by the School, while in Cyprus the (retiring) Director completed his excavation at Paphos. At Knossos, Mr Sackett completed the excavation begun in 1967 of the post-Minoan overlay of the Unexplored Mansion, and Mr Popham, Assistant Director of the School, excavated the late Minoan levels, which had been extensively robbed in places. The main rooms of the building had been destroyed in LM I11 AI period, though some were remodelled and reused later in the LM I11 B. To this latter period belongs the figurine with raised arms (PL. xvIIIa).

The Grottes d'Arcy, situated on the main road (RN 6) between Auxerre and Avallon, are the closest big caves to Paris (FIG. I). Between the 16th and the 19th centuries the most distinguished visitors, from Louis XI11 to M. de Buffon (1740), marvelled at the immense galleries adorned with stalactites at the Grande Grotte. The caves still attract many tourists. All nine of the Arcy caves have a generally southerly exposure, and they have been cut into-some of them through-the south flank of a Jurassic limestone massif, or promontory, around which the Cure River flows in a large bow between Saint-MorC and Arcy-sur-Cure. Actually this area is on the border between the southwestern limits of the Seine Basin and the extreme northwestern extension of the granitic massif of the Morvan, where the Cure has its source. This complex of caves lies on the left bank of the Cure just west of RN 6 some 12 km. south of (i.e. upstream from) the confluence of the Yonne and the Cure, at a distance of just over 27 km. south-southwest of Auxerre and about 17 km. north-northwest of Avallon. Here the Cure (the mean elevation of which at this

The name Riotinto has something of a magical connotation in the world of mining. It has been called the geologist’s paradise because at almost no other place on the earth has nature exposed in one spot such richness and variety of minerals. The floor of the bed of the richest areas in Riotinto is made up of a mass of porphyry and pyrites overlain by an oxidised cap. At the zone of contact between the two levels is an enormous deposit of silver, gold and other metals which today, as in ancient times, supports a flourishing industry.

Professor Stuart Piggott's book is the first serious attempt for over forty years to deal systematically with a full range of sources concerning the druids. Sir Thomas Kendrick's study The Druids, A Study in Keltic Prehistory (London, 1927; re-issued New York, 1966), still enjoys an enviable reputation as a comprehensive treatment of the varied source-material on which an account of the druids can be based. It would be quite wrong to suggest that scholars have not in the meantime tried to understand more fully some of the complexity of this material, but we can fairly claim that it is only within the last nine or ten years that we have had a spate of publications attempting a new critical analysis of various aspects of this field of study. Incidentally, an earlier work of considerable importance that is not included in Piggott's bibliography is J. Vendryes, 'La religion des Celtes', in Les rel%ions de I'Europe ancienne, iii ('Mana', Introduction rf I'histoire des religions 2), Paris, 1948.
