OLERON, Laws of, etc, A media-val code of maritime laws promulgated and published some time during the twelfth century, by Eleanor, Duchess of Guienne (Aquitaine). These laws consisted of a collection of the judgments of the maritime court of Ol^ron, together with a compilation of the customs and usages of the sea having the force of law among tlic marinex's of that island, which was a shipping centre. Some years after this codification was made and published in Oleron. Richard I., son of Eleanor, introduced the whole body of these laws into England, They were one of the sources of the maritime laws of Visl)y, and were pub- lished in and had an important intluence on the maritime laws of probably all the countries of Europe. The modern English and American maritime law has been developed from these laws as a basis, influenced by the Rhodian maritime laws, the laws of Wisby, the civil law, and the customs and usages of those engaged in shi]v ping.
