Elements symbols & vision Options

Hi to everyone!
In this period I'm writing down something on the Elements...some questions that I'm still trying to answer:

1) In ancient philosophy the ligthest element was the Fire; today it is the Air. When and why this switch did occour?

2) What were the elements in the vision of the Golden Down?

Thanks (IMG:style_emoticons/default/smile.gif)

Somewhere among my archives, I probably have an answer to your question; but I bet you don't want to wait weeks for me to find it (IMG:style_emoticons/default/13.gif)

I thought this link was quite interesting, I am not trying to confuse you, but just to show that each system has placements that works for it.

Having said that, in one of the very first rituals I did, I place two of the elements in the 'wrong' place and had an angel or some entity come along and swap them over. What I would dearly love to remember is where I got the original ritual from and then I also might understand the placings and reasons for them.
