Join Daniel Docherty and master stone-mason Nicholas G. Durnan for this week-long course where participants will learn the principles of Order in Space through a deep study and immersion in the five platonic solids. Daniel will lead the first two days where we will familiarise and befriend the forms as we draw, model and weave them in various ways and at various scales. The focus of the Thurs/Fri/Sat sessions will be on the carving of the forms in stone. It is likely that particpants will be able to carve a full set of all five 'Platonic' solids.
