This study explores the way in which our picture of the Levantine Epipalaeolithic has been created, investigating the constructs that take us from found objects to coherent narrative about the world. Drawing on the treatment of chipped stone, the fundamental raw material of prehistoric narratives, it examines the use of figurative devices - of metaphor, metonymy, and synecdoche - to make the connection between the world and the words we need to describe it. The work of three researchers is explored in a case study of the Middle Epipalaeolithic with the aim of showing how different research goals and methodologies have created characteristics for the period that are so entrenched in discourse as to have become virtually invisible.Yet the definition of distinct cultures with long-lasting traditions, the identification of two separate ethnic trajectories linked to separate environmental zones, and the analysis of climate as the key driver of change all rest on analytical manoeuvres to transform objects into data.

Recent work on a sample of the chipped stone from one of the late Mesolithic shell midden sites on the Inner Hebrides island of Oronsay has shown that the assemblage was created using bipolar and platform technologies, with an unexpected element of narrow blade technology shown in cores and core trimming elements, suggesting that there may have been links between this classic ‘Obanian’ assemblage and the more typical Mesolithic narrow blade technology. Findings raise questions about the relationship of settlement on the island to Mesolithic settlement rounds and to the transition to the Neolithic.

The exact pattern, process and timing of the human re-colonization of northern Europe after the end of the last Ice Age remain controversial. Recent research has provided increasingly early dates for at least pioneer explorations of latitudes above 54°N in many regions, yet the far north-west of the European landmass, Scotland, has remained an unexplained exception to this pattern. Although the recently described Hamburgian artefacts from Howburn and an assemblage belonging to the arch-backed point complex from Kilmelfort Cave have established at least a sporadic human presence during earlier stages of the Lateglacial Interstadial, we currently lack evidence for Younger Dryas/Greenland Stadial 1 (GS-1) activity other than rare stray finds that have been claimed to be of Ahrensburgian affiliation but are difficult to interpret in isolation. We here report the discovery of chipped stone artefacts with technological and typological characteristics similar to those of the continental Ahrensburgian at a locality in western Scotland. A preliminary analysis of associated tephra, pollen and phytoliths, along with microstratigraphic analysis, suggest the artefacts represent one or more episodes of human activity that fall within the second half of GS-1 and the Preboreal period

The relationship between rock art and the material qualities of the rock surface on which it is executed is investigated. The case study of Revheim, Rogaland, Southwest Norway, is the starting-point for a discussion on the way in which the contours of the rock, quartz outcrops and the flow of water across the rock surface affect the placement of images on the rock. It is argued that a fuller examination of the interrelationship between rock and rock art provides a more coherent interpretation of rock art images.

The Perthshire stone circle of Croft Moraig was excavated 40 years ago and is usually taken to illustrate the classic sequence at such monuments in Britain. A timber setting, accompanied by a shallow ditch, was replaced by two successive stone settings. The pottery associated with the earliest construction was dated to the Neolithic period. A new analysis of the excavated material suggests that, in fact, the ceramics are Middle or Late Bronze Age. They provide a terminus post quem for at least one of the stone settings on the site. Further study of the evidence suggests an alternative sequence of construction at Croft Moraig, involving a change in the axis of the monument. It seems possible that other stone and timber circles were equally late in date and that their period of use in Britain and Ireland may have been longer than is generally supposed.
