"The swastika is indeed a sun symbol from antiquity, appropriate in many themes & on many occasions. Like flood legends, the swastika (in various recognizable styles) is one of many symbols found thru-out ancient civilisations having no possible contact (as we understand contact) with each other. Usually it meant the sun, in its scheme as "the wheel of life". (Mayan, I believe.) It was also a popular good luck symbol. For example, it can be found on pre-1930 American New Year's greeting cards.
A white swastika on a black field was the flag of an American Boy Scout Troop from its founding to some point in the 1930's, when the Troop itself voted to discontinue its use, in light of the rise of the Nazi regime (...) The symbol itself may still be found as an architectural element, decorating sufficiently aged temples to whatever deity is involved."
