Small islands offer archaeologists interesting and manageable subjects for survey and excavation. The recent work on Adriatic islands reported here examines occupation during the 3rd millennium BC, showing how sailors exploited islands for trade, control and raw materials.

Boxgrove in Sussex has been in the headlines for its human bone (‘the first Englishman’); more to the research point is its superb in-place deposits of debris from handaxe-knapping. This is a timely moment to look once again at the reports of Worthington G. Smith, who a century ago recognized, amongst the scores of sites with river-rolled handaxes, rare deposits of a more informative character.

A glance at the archaeological literature of the last dozen years demonstrates all too clearly that the popularity of the 'invasion hypothesis' in Irish archaeology is quite undiminished. An almost incessant stream of immigrants appears to have tramped ashore from the Mesolithic period to the Iron Age. Even reckoning those pre-eminent invaders, the Beaker Folk, as merely a single influx, over a dozen significant prehistoric population movements are claimed by a variety of writers. The general picture presented suggests that Ireland throughout much of her prehistory was, if not an archaeological Ellis Island, at least a desirable landfall for the land-hungry, the dispossessed and the adventurous of most of the rest of Western Europe. Major changes and innovations in the archaeological record-in monument or artifact typemay conceivably be the result of either independent invention, or diffusion or of a combination of the two. The occurrence of megalithic tombs in very different cultural and chronological contexts in Western Europe, India and Japan, for example, is an instance of independent invention.

Scanning electron microscopy provides an insight into the lapidary techniques of the ancient Near East. Engraved features on quartz cylinder seals have been compared to those produced experimentally, leading to a radical reassessment of the date for the introduction of the engraving wheel.

Profound changes occurred in central and northern Europe towards the end of the 3rd millennium bcX, when a uniform pattern of settlement, burial and material culture-the Corded Ware complexreplaced the diversity of the middle neolithic groups of the TRB (or Funnel Beaker Culture). Collective graves and large settlement sites gave way to individual burials in a largely dispersed pattern of settlement based on small sites. This was accompanied by a spread of sites into hitherto uncolonized areas, and a greater variety of locations used for settlement. This major change might at first seem to indicate a complete collapse of the earlier system, with an undifferentiated pattern replacing the apparent beginnings of hierarchies indicated by the Middle Neolithic. Kristiansen ( I 982) has recently suggested for Denmark that the middle neolithic system disintegrated, fitting a model of cyclical tribal development. It is suggested here, however, that the transformation of the middle neolithic pattern is better seen as a changed structure, which does not involve concepts such as disintegration or collapse, but marks an important shift in the organization of neolithic societies.

Since 2012, the French Mission in Oman has discovered several Palaeolithic sites in the south-eastern foothills of the Sufrat Dishshah (a hill of the Sufrat Valley/Wādī al-Сufrāt), in the Adam region of north-central Oman. These sites are attributed to the Lower through to the Late Palaeolithic (Bonilauri et al. 2015). The 2016 field season was dedicated to further investigation of the previously identified sites of the Sufrat Dishshah area. A number of additional artefacts were located and studied on site; four artefacts—two bifaces and two Nubian cores—were retained for further study. These finds have particular importance for the understanding of Middle Palaeolithic variability and cultural diffusion in Oman, and they represent one of the most significant results of the 2016 Adam expedition.

Is the term shamanism being applied uncritically and subjectively to rock art? J D Lewis - Williams responds to criticism from Alice B Kehoe and Mairi Ross featured in earlier numbers of Antiquity.

Prehistoric (Bronze Age) settlement has been little explored in the Yemen. Here, we report on new research at the small, semi-urban site of Hammat al-Qa in the Dhamar region of Yemen.

Readers of recent issues of ANTIQUITY will have doubtless been struck by the passions which can be aroused by discussions concerning concepts of prehistoric as well as present-day ethnicity. Here the Megaws round off a Celtic trilogy of papers with what will surely not be the last word in an important debate.

Investigation of a partially waterlogged Neolithic site, on an islet in a Scottish Hebridean loch, showed that early strategies of exploitation were already environmentally damaging. Loss of soil fertility through intensive ploughing is well-documented, but stripping the turf can be equally damaging to the environment. Working on the lake settlement of Eilean Domhnuill in North Uist, the authors show that turf was cut for building material and used as fuel and that this practice contributed to a rapid degradation of the land surface through erosion.

The authors report new understanding of the prehistoric monuments of Hadramawt (Yemen) using archaeological fieldwork, linguistic terminology and ethnography. The stone tombs, platforms and alignments are shown to have experienced particularly interesting life histories. Passing travellers add stones and bury camels, shrines are reconditioned and dismantled to construct goat pens. It is clear that only this kind of multi-disciplinary expertise can hope to define the prehistoric sequence in an arid and rocky mountain landscape in which non-literate pastoral peoples have left few other traces.
