who invented the meaning of the middle finger
The finger The gesture dates back to Ancient Greece and it was also used in Ancient Rome. Historically, it represented the phallus. In some modern cultures, it has gained increasing recognition as a sign of disrespect, and has been used by music artists (notably more common among hardcore punk bands and rappers), actors, celebrities, athletes, and politicians. Most still view the gesture as obscene. The index finger and ring finger besides the middle finger in more contemporary periods has been likened to represent the testicles.[2]
V sign A commonly repeated legend claims that the two-fingered salute or V sign derives from a gesture made by longbowmen fighting in the English and Welsh[27] archers at the Battle of Agincourt (1415) during the Hundred Years' War, but no historical primary sources support this contention.[28] This origin legend states that archers who were captured by the French had their index and middle fingers cut off so that they could no longer operate their longbows, and that the V sign was used by uncaptured and victorious archers in a display of defiance against the enemy. However, it was common practice in warfare of that period to summarily execute common soldiers, since they held no ransom value.
