While not exactly the same, the concept of "whale drift" has existed in Icelandic law [1] for almost 8 centuries, and still applies today. It specifies to whom a whale carcass would belong to, depending on the situation, and so forth. The concept of "whale drift" also exists in the Icelandic language, and is used to point out an event as a stroke of great luck.
