Jonah, английский
- A person (either a sailor or a passenger) who carries a jinx, one whose presence on board brings bad luck and endangers the ship.
- This name for a shipmate or passenger who brings bad luck on board is based on a story that appears in the hebrew tanakh, christian bible, and islamic q’ran. jonah (or jonas) tries to escape god’s command by sailing away, but his disobedience causes the lord to send “a mighty tempest ... so that the ship was like to be broken” [jonah 1;4]. the sailors cast lots to determine whose transgressions have brought the storm upon them and throw jonah overboard. the seas instantly calm, and three days later jonah comes to the shore, still alive. what happened during those days is open to conjecture. according to the story, he had been swallowed by a “great fish” (commonly considered to have been a whale, but possibly a large shark) which vomited him up after he begged god for forgiveness. this is far-fetched, but not impossible (see bartley’s ordeal) although it is difficult to understand how three days in stomach acid would not have burned out jonah’s eyeballs. jonah himself never mentions a fish but says to god: thou hadst cast me into the deep, in the midst of the seas; and the floods compassed me about; all thy billows and thy waves passed over me.... the waters compassed me about, even to the soul; the depth closed me round about, the weeds were wrapped around my head. ( jonah 2:3,5). based on this, it has been hypothesized that “great fish” was an ancient seafarer’s term for a powerful current, which swept jonah away and carried him to shore.
