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.

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.
