Aye, the word "swastika" is thought to be that, but we find the symbol itself going much further back. There are several early examples from the Ukraine, carved on ivory, dating from 18000-15000 BC. Multiple swastikas have been found on Mammoth tusks in Russia, c.7000 BC - there's plenty of truly early material on this 'ere swirlygig; and though we get the usual "good luck" or "sun" symbolism attached, it's primarily the life-force or creativity it represents.
