Nice site. I've seen some human figures with 'hats' so that's what my mind tells me, it looks horned too! Rainbow sounds a tad romantic, reality is often quite 'mundane', though the 'disc' could represent the sun or moon in my opinion. Whereabouts is that? Hope you find it, rock inscriptions are a real pain in the neck to find...especially with sheep chasing (?), funny that one!
