Ooh, symbols

One of my favourites.
I've always seen the reading of symbols as being similar to the reading of costume. I'm gonna go a little off topic here, but this is the best way I can explain how I see it.
There are two types of clothing - costume and fashion. Fashion is cnstantly changing and has little meaning as a language due to its ever changing nature. All you can gleen from someone wearing fashionable clothes is that they have money, are at least influenced by Western society, and are interested in keeping up with the fashions.
Costume, on the otherhand, is reasonably static and there are many meanings
within the costume. Costume is things like national dress, ceremoial dress, tribal tattoos, military uniform etc. The chevrons on the arm of someone in the army only have meaning if you are aware of the 'dictionary' that someone within that culture would know.
There are tribes where the location of the tattoo is just as important as the desing; where the hair style denotes your rank; where how many children you have is incorporated into a pattern of raised scars. These are all things that only those within the group can be aware of, and very few outsiders are privy to that information.
As I said, this is how I see symbols. The spiral, the star, suns and moons, all are symbols which are found in many belief systems and generally have the same meanings. Usually, the sun means life - it's necessary for crops to grow and for warmth. But it can also destroy if there's no rain or breeze. The spiral is one of the most pleasing shapes, and is one that occurs the most in nature - the fibonacci spiral being the case in point. It's natural that those who walked this earth before us would have noticed this an used it in their art work. But we have no way of knowing
exactly what they saw in these symbols. All we know is how we see the now.
We can pretty much say for certain though, that depending on where a culture was in the world would change the meaning of these symbols for them. Someone living near the equator would have a different perception of the sun to someone living nearer the North Pole. Rain would be seen differently by someone in the rainforest compared with someone in the desert.
It's not just symbols which are global, there are legends as well. Dragons and a great flood are the two which stick out in my memory. And again, these legends were seen differently depending on where on the planet the culture was based.
I guess what I'm trying to say is that we cnanot be certain
wherethese symbols came from,
why they were used, or
what they meant. Symbols like the swastika which have a recorded history can be traced and the change of meaning can be lamented. But to me, that's simply the changing of a visual language.
Look at the way the English language has changed. Who uses 'gay' to mean joyous and fun anymore? It's a word which has been appropriated for a different meaning, and will probably never be used for it's original purpose. My personal favourite is 'peculiar'. We use it now to mean odd, strange, not normal. But it used to be another word for indigenous - if something is 'peculiar to an area' it's normal in that place.
The best we can do is be aware that simply because we are told that this symbol has 'always' meant A, doesn't mean that it never meant B. Ancient symbol, yes, but not always an ancient meaning. This is where we study and come to our own conclusions. If an image speaks to you, then it has a meaning to you, but it might mean nothing to anyone else.
Think I rambled a bit there, but hope it made sense
