Astronomy, Oral Literature and Landscape in Ancient Hawai¹i Clive Ruggles School of Archaeology and Ancient History University of Leicester, U.K. The nature of ancient and traditional peoples¹ interest in the skies, and how this was reflected in the design of some of the most famous monuments in the world, is something that continues to engender a remarkable degree of popular interest. Over the years, debates on this topic have also attracted leading archaeologists, astronomers, anthropologists, engineers, historians of science, statisticians, and many others, yet have all too often finished up generating far more heat than light. Only in recent years has archaeoastronomy matured from being a rather inconsequent pursuit hovering on the fringes of established academic disciplines into an identifiable "interdiscipline" working to develop secure theoretical and methodological foundations in its own right. By studying how spatial patterning in the archaeological record relates to the motions of the heavenly bodies, together with other forms of archaeological and cultural evidence, we can gain valuable insights into how groups of people in the past interpreted what they saw in the skies and framed their own actions in harmony with that understanding. This is of central importance in trying to address a variety of broader questions concerning people¹s perceptions of the world and the ways in which they manipulated their "cosmological" knowledge for various purposes. Ancient Hawaiians, like many indigenous communities the world over, had a powerful and detailed understanding of their relationship with the natural world, which they encapsulated in myth and constantly reinforced through sacred activities located in space and time in relation to important places in the landscape and the motions of the celestial bodies. This seminar will examine two recent claims in the light of new fieldwork carried out, mainly on the island of KauaŒi, in the last three years. The first is that astronomical alignments involving distant topographic foresights, viewed from heiau, formed an important component of Hawaiian sacred geography. The second is that certain sacred ceremonies, performed at particular heiau, were scheduled in relation to observable astronomical events. Studying the specifics of Hawaiian cosmological and astronomical knowledge occupies an important place in the wider study and understanding of Hawaiian culture, but it also occupies an important place in the methodological development of the discipline of archaeoastronomy as a whole. This is because it forms a methodological "halfway house" between two much-studied areas: prehistoric Europe, where the evidence is exclusively from the material record, consisting of human-made architecture such as conspicuous monuments and their spatial relationships with features in the landscape and sky; and Mesoamerica, where the historical and written records dominate over the archaeological and landscape evidence. In Hawaii we have access to a rich oral history, including some very specific references to places in the landscape and, apparently, to astronomical alignments. Yet archaeologists are generally wary of basing reconstructions on such evidence because oral histories are notoriously fluid, and the provenance of particular traditions is often highly uncertain. The seminar will address the key issue of how we find the best balance between these two very different types of evidence.
