There are at least 48 identified prehistoric stone circles in Scotland. In truth, very little is known about the people who erected them, and ultimately about what the stone circles were for. Most stone circles are astronomically aligned, which has led to the modern debate about why the alignment was significant. The megaliths certainly represented an enormous co-operative effort, would at the very least have demonstrated power and wealth, and being set away from any dwellings probably served a ceremonial, or perhaps religious, purpose.
Observations at the site of the stone circles, of solar, lunar, and stellar events, have already cast light on some of the questions about the construction and use of ancient megalithic observatories.
In his capacity as manager of the Parks Department Astronomy Project, author Duncan Lunan designed and built the first astronomically aligned stone circle in Britain in over 3,000 years. ''The Stones and the Stars'' examines the case for astronomical alignments of stone circles, and charts the development of a fascinating project with a strong scientific and historical background. The work was documented in detail by the artist and photographer Gavin Roberts, and this archive has been added to since - so an appropriate selection of illustrations will bring the project vividly to life.
