Mysterious 5000 year old Neolithic carved stone ball from Towie, Scotland with spiral designs. Over 430 examples have been found, with varying form, purpose unknown, but inevitably described as ‘weapons’ or ‘symbols of power’. The geometry reminds me of the Platonic Solids.
Photos: National Museum of Scotland. A wonderful place.
