What is the historical origin of the salute?

The origin of the salute can be traced back to the practice among knights in the medieval period. When knights met each other, they would lift their visors to reveal their faces, a gesture that symbolized respect and recognition. This act of lifting the visor was a way to show that one was not a threat and to signify honor between peers.

This historical practice evolved over time and influenced the modern military salute we see today, where it serves as a formal gesture of respect and greeting among service members. It represents recognition of rank and authority, though its roots in chivalry and respect remain significant in understanding its initial meaning.

While the other options present interesting ideas about gestures used in historical contexts, they do not accurately reflect the specific origins of the salute as it is understood today.
