Successive paradigms by which they have been interpreted have been examined. Their Late Neolithic and Early Bronze Age cultural contexts have been discussed. The circles have been described and their physical charac teristics, diameter and number of stones, and their associated features analyzed. Two hypothesized primary functions have been examined, that of astronomical observa tory and that of religious-ceremonial site. It was con cluded that the circles were not constructed to serve primarily as astronomical observatories, but rather that an astronomical orientation, present at many of the sites, indicates that observance of midwinter solstice was prob ably an integral part of the religion of their builders. xi A religious-ceremonial function was found to be the more likely primary function for the majority of the circles. Analysis was made of the distribution of the circles in relation to three models of social interaction (coopera tion, competition, or autonomy) among basic population units (extended families) and inferences drawn concerning the social organization of the builders. It was concluded that no one model alone could explain the distribution of the circles, but that different processes were operating in different areas in a transitional social evolutionary stage between the more egalitarian Neolithic and more hierarchi cal Middle Bronze Age. xii INTRODUC'riON The stone circles of Ireland (map, Figure 1) are a type of megalithic structure or monument. The term megalithic refers to the massive stones used in these construe- tions, built without the use of mortar, rather than to any particular group of people who constructed such monuments. Many peoples have built megalithic structures. Megalithic monuments in Europe consist of tombs (dolmens), single standing stones (menhirs), and stone circles. When one speaks of stone circles, Stoneheng.e, because it is so well known, immediately comes to mind. There is, however, a distinction between henges and stone circles. A stone circle is usually defined as a ring of stanq~ng.stones
