Handcuffs

Iron "handcuffs" (= "chains") from the Roman Period on display in the Archaeological Museum in Durrës, Albania. "Chains" are mentioned over 20 times in the New Testament! For Example:

Acts 12:6 The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance. 7 Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and the chains fell off Peter’s wrists.
