I've done a little trawling around the WWW and this Simon stuff is getting interesting.
I've found one site that goes on about Mug Ruith a famous Irish druid. Anyway this Mug character was a mate of Simon Druid and is believed by some to be an early sun god. The bit that caught my attention was the description of Mug "He is described as either one-eyed, or blind in the tales and he can dry up the lakes with his breath or raise storms."
A one eyed storm raiser, hey hey were straying into Cailleach/Bodach country here.
