Archaeoastronomy

… is the study of beliefs and practices relating to the sky in the past, especially in prehistory, and the uses to which people's know- ledge of the skies was put.

Heiau, ‘Āina, Lani published

Heiau, ‘Āina, Lani: the Hawaiian temple system in ancient Kahikinui and Kaupō, Maui, by Patrick V. Kirch and Clive Ruggles has been published by the University of Hawai‘i Press. The book represents the results of a joint fieldwork project by the two authors, spanning more than 15 years, in the south-eastern coastal area of the island of Maui. There is a remarkably well preserved archaeological landscape here containing pre-conquest house sites, walls and terraces for dryland cultivation, and including scores of temple sites (heiau), many of which are newly discovered and reported in the book for the first time.

Heiau, 'Aina, Lani is a collaborative study of 78 temple sites in the ancient moku (districts) of Kahikinui and Kaupō. The title of the book means "Temples, Land, and Sky" and reflects the integrated approach taken by the authors, combining archaeological and archaeoastronomical evidence (detailed mapping of the structures, precise determination of their orientations, and accurate dating) which allows them to offer some provocative interpretations of the complex relationships between the Hawaiian temple system, and landscape, and the heavens (the “skyscape”). The book repositions the study of heiau at the forefront of Hawaiian archaeology and also demonstrates the successful integration of archaeoastronomy into broader investigations of archaeology and landscape.

Stonehenge avenue and “Bluestonehenge”

Stonehenge avenue runs for almost 3km up to Stonehenge from West Amesbury henge, by the banks of the River Avon. Excavations in 2009 suggested that this location once held a circle of bluestones that were subsequently moved to Stonehenge, around the same time that the ditches of the avenue were dug.

The final stretch of the avenue leading up to Stonehenge is famously aligned upon winter solstice sunset and summer solstice sunrise, as is the axis of Stonehenge itself. An excavated section across the avenue in 2008 yielded a big surprise, however…

Archaeoastronomy helps to identify a ceremonial gathering place in pre-contact Hawai‘i

Ethnographic accounts indicate the existence in the Hawaiian Islands at the time of European contact of special places where people would gather during the Makahiki period, to offer tribute to the priests of the god Lono and for sports and other recreational activities. However, no such place had been positively identified to date. Now, through a combination of mapping, excavation, radiocarbon dating, archaeoastronomical analysis, and ethnography, a strong candidate has been identified in the uplands of western O‘ahu.

Nā Inoa Hōkū published

 

This is an extensively revised and extended version of Nā Inoa Hōkū: Hawaiian and Pacific star names, first published in 1975 by Hawaiian scholars Rubellite Johnson and John Mahelona and still widely regarded as a definitive source of reference for anyone studying the use of astronomy in Polynesian voyaging as well as the nature and development of Hawaiian ritual and calendrical practices. This new edition includes new translations of many key original Hawaiian sources from the mid-19th century onwards.

 

Published in August 2015, Nā Inoa Hōku is available from the University of Hawai‘i Press world-wide apart from Europe, where it can be ordered from Oxbow/Casemate. See the Ocarina Books website for further details.

New orientation data for the Giza Plateau, Egypt

A paper presenting new basic data concerning the orientation of the three great pyramids and associated structures on the Giza Plateau has appeared in the August 2014 issue of Journal for the History of Astronomy.

 

A Polynesian sighting wall

 

Ke Pānānā Kahiko o Hanamauloai

A paper by Patrick V. Kirch, Clive Ruggles and Warren Sharp published in the March 2013 issue of Journal of the Polynesian Society describes a unique monument on the Hawaiian island of Maui interpreted by the authors as a “sighting wall” built in the 15th century to commemorate long-distance Polynesian voyaging.

 

The authors reach this conclusion by combining archaeological and archaeoastronomical evidence, together with precise Uranium-series dating.

 

Desert labyrinth

 

A paper published in the December 2012 issue of Antiquity describes a previously undocumented geoglyph in the Nazca desert, Peru. This 4.4km-long labyrinth was originally discovered by Clive in 1984, relocated and surveyed 20 years later, and is now interpreted by integrating the scientific data and conclusions drawn from the first-hand experience of walking it.

A Mesolithic calendar?

 

A team of British archaeologists has discovered what they believe to be the oldest calendrical monument known anywhere in the world, created by hunter-gatherer societies in Scotland and dating back to around 8000 BC.

 

The site, at Warren Field, near Crathes, is broadly aligned in the direction of midwinter sunrise, which was framed among prominent hills to the south-east. But it also appears to mimic the phases of the moon in order to track lunar months over the course of a year.
