I appreciate that sometimes I have some 'wacky' ideas....but if we all thought the same way....progress in knowledge would be greatly slowed. (well that's my excuse anyway
) but I'd like to throw this idea into the discussion.
The phallic symbolism of the sword has been shown to be relevant to many cultures and time periods.....
Could it be that the 'clouds' indeed symbolises 'heaven' , the repetative side motif symbolising 'life' (if it is a form of flora ) but, shaped in a phallic design (the 'bringer' of life? Male virility?). The 'rising' symbols perhaps representative of male, female (human seed? re-incarnated souls?). The Sword itself, is the 'bringer' of death, in combination with the 'life' symbolism, we end up with a depiction of the cycle of life........birth (re-birth?) , growth and death.
.........and afterall 'The pen_is mightier than the sword'...
Interesting thread, iconography, symbolism etc is an important part in the study of ethnographic weaponary. If we could 'crack' the lost meanings ...we would get 'more of a feel' of how these items were viewed through the 'eyes' of their original owners.
