Did you know?

In Coleridge's Rime of the Ancient Mariner, an old seaman tells of how, by shooting a friendly albatross, he had brought storms and disaster to his ship, and how as punishment his shipmates hung the great seabird around the mariner's neck and made him wear it until it rotted. The word mariner has occasionally been used to mean simply "explorer", as in the famous Mariner spaceflights in the 1960s and '70s, the first to fly close to Mars, Venus, and Mercury.
