Page "Quiver" Paragraph 4

Back quivers are secured to the archer's back via straps, with the nock ends protruding above the dominant hand's shoulder.

Arrows can drawn over the shoulder rapidly by the nock.

While popular in cinema and art for depictions of medieval European characters ( such as Robin Hood ), this style of quiver originated with Native American tribes of North America, and was never used in medieval Europe or Asia.
