I’m sure there is a good scientific reason behind the similarities of the two.
Fasces (/?fæsi?z/, a plurale tantum, from the Latin word fascis, meaning “bundle”) is a bound bundle of wooden rods, sometimes including an axe with its blade emerging. The fasces had its origin in the Etruscan civilization, and was passed on to ancient Rome, where it symbolized a magistrate’s power and jurisdiction. The image has survived as a representation of magisterial power. A secondary meaning of the bundling of sticks may have been “strength through unity”. Fasces frequently occurs as a charge in heraldry, and should not be confused with the related term, fess, which in French heraldry is called a fasce.
