Excavations at Mad Mans Window, Glenarm, Co. Antrim: Problems of Flint Exploitation in East Antrim

This study examines the archaeological significance of the material from a group of Neolithic chipping floors rescued during the rebuilding of the Antrim coast road, at Mad Mans Window, south of Glenarm, Co. Antrim. It shows that the lithic production strategies vary significantly between assemblages although it is presumed that they are all Neolithic in date and come from the same area of coast. It is apparent that flint axe production was of limited importance on these sites and that in spite of the abundance of flint available along the Antrim coast, relatively few polished flint axes were manufactured. Instead the numerous flint caches found in adjacent parts of the north-east of Ireland tend to produce scrapers and blades. Hoards containing arrowheads may be confined to the Bronze Age.Around 300 polished flint axes and roughouts are known from Ireland. These are frequently small and only partially polished. A limited number of highly polished axes with ground flat side facets have been designated sub-type A. The tendency to use porcellanite rather than flint for axe manufacture may be due to its ability to withstand robust shock.During the last 100 years, the role of flint as a key resource in the stone age of north-eastern Ireland has always been recognized but this has usually led to an uncritical assumption as to the paramount importance of flint. Work in recent years has shown that its significance in attracting and retaining Mesolithic settlement may have been over-emphasized.The role of the flint industries in the Irish Neolithic in this region has never been properly assessed, either in relation to older Mesolithic manufacturing traditions or in the broader context of supply to the Neolithic communities of this part of Ireland.In particular, good or even reasonable quality flint is usually only exposed in Cretaceous outcrops along a narrow strip on the edge of the basalt plateau and, therefore, has a very limited availability in parts of Co. Antrim as well as parts of Counties Down and Deny. As a contrast, erratic and beach flint is available in some quantity down the east coast of Ireland from Co. Down to Wexford. A second potential constraining factor is that unlike Britain, where flint was exploited for axe manufacture in the east and other rocks in the west, flint sources and porcellanite for axe manufacturing are both found adjacent to each other in the same corner of Co. Antrim. In particular, a number of more substantial chipping floors of Neolithic age are known, e.g. the opencast quarry sites at Ballygalley Head. The purpose of this study is to assess the role of flint production on the Antrim coast with particular reference to its significance in the Neolithic. This topic will be developed in the context of an analysis of the material found at Mad Mans Window near Glenarm.
