Set of codes relating to maritime law thought to have been instituted in England by Richard I. They regulated all relationships between captains and their men, and their employers; they also had to do with the laws of wrecks. Some of the laws deal with violence onboard ship, e.g. if murder was committed at sea, the murderer should be tied to the body of the victim and thrown overboard. Another states that for punching someone a man should be ducked three times. They were first printed in 1494. (An equivalent collection of laws, though of earlier date, pertaining to France and Spain, was known as the Consolat del Mar.) The laws are to be found in the Black Book of the *Admiralty. Oleron is a small island in the bay of Biscay. -
