AN ancient hexagram encoded in the Wessex landscape, linking Stonehenge, Avebury and Glastonbury, as well as holy springs and wells, Knights Templar sites, and other sacred places, has been discovered by Dorset researchers.

Peter Knight and his partner Toni Perrott launch their book on the "Wessex Astrum" – "astrum" from the Latin for "star" – at Glastonbury Town Hall next Wednesday evening, and follow this up with a presentation at their fifth annual Convention of Alternative Archaeology and Earth Mysteries at Poundbury, near Dorchester, on the following Sunday.

Peter said: "More than 500 miles of alignments form this incredible landscape wonder, The sacred hexagram is of very ancient origin. It represents the harmony of the universe." Author of five books on sacred sites and earth mysteries, Peter is chairman of the Dorset Earth Mysteries Group.

As well as Peter and Toni, speakers at the convention include Nicholas Mann, Phillippa Glasson, Hugh Newman and Shaun Kirwan, from Glastonbury, and Jonathan Harwood, from Dorset.
