Pythagoras Flag

The pentagon for Pythagoras is the symbol of the number 5, the number of love and marriage. The pentagon is also the symbol of the pentagram, symbol of the brotherhood, called "health" perhaps in honor of the Greek goddess Hygeia.   According to some researchers the discovery of the number F is attributable to the followers of Pythagoras (5th century BC), also due to the interest of the confraternity towards the pentagon, associated with the number 5.
