An Archers Thumb Ring.
Made from bronze. Size 1″ x 1 1/2″ inches.
Dated 12th – 14th century AD.
Mainland European and some far Eastern archers always used their thumb to pull back the bow string. These thumb rings were designed to protect the inside of the thumb while drawing the bow string back. English and Welsh archers used their first two fingers, index and middle fingers to draw the bow and never needed the use of a ring.
