An archers with a quiver on his back is a movie icon which is widespread throughout the world.
But putting arrows in a quiver on your back is not a good solution.
It is bad in motion and the archer cannot see his own arrows, as he has an enemy in front of him. He must focus on his quiver, which makes him vulnerable.
Past archers often had different types of arrows simultaneously in his quiver but since the quiver is on his back, he cannot see which arrow he takes.
Placing the quiver in the belt solved most problems, and if the archer is horseback, the quiver could be placed on the horse in front of the rider. These methods were the most common ways to use a quiver.
