Agree, thanks for the links. I do think that some of those things depicted in the paintings, as some of the Chunkey discoids may have something to do with UFOs, but that's just my opinion of course. That's why I'm asking myself if the game of Chunkey may have had some religious context once that maybe got lost in history. From wikipedia, I only got that it was somehow connected to the figure of the "falcon dancer" but that doesn't tell me much. I hope that Mr Stanford and Chris have some insights there.
I guess it's not too far a stretch to think that unusal objects in the sky may have been seen as religious signs or omens and thus found their way into religious art or religious rituals. Maybe later the original descriptions of the real sightings were forgotten and the depicting became stylized or glorified. I guess even sceptics will have to admit that this thing in the sky over Mary's shoulder is remarkable, especially with the guy looking up to it, which indicates that it might not be just a symbol but a real object.
Oh and: Peace, my brothers in discovery. Sometimes on the internet, things get posted that shoudn't be taken too serious or they may sound offending but weren't really meant that way. Zutch sinks happens says ze Bratgeist.
