Acts 16:24. Who, having received such a charge, thrust them into the inner prison, and made their feet fast in the stocks.
Some would understand by ξυλον “stocks,” simply a bar of wood to which the feet of the prisoner were chained. Others suppose the instrument to have corresponded to the modern stocks, consisting of a frame of wood in which the two feet, separated far apart, were placed. There were some ancient stocks in which were five holes for fastening feet, hands, and head.
In Ceylon, at the present day, an instrument similar to this is used, only the head is allowed to be free.
The use of the stocks is very ancient. See Job 13:27.
