Sunk by something big, mythological, and white
Somebody actually photographed the iceberg that sank the Titanic.
Let us therefore for a minute’s worth, o my brethren, imagine how he ran into his ship cabin three or four decks lower, got out his camera, ran back, built it up on its three legs, and took the picture in the middle of the raging stampede around him, and how the film with him to the ground of latitude 41-46N, longitude 50-14W, until it was recovered by a bunch of dauntless frogmen and given to developing — before we are disillusioned by the fact that the pictures were taken by the chief steward of the Hamburg-American liner Prinz Adelbert on the morning of April 15, 1912, a few miles south of where the Titanic went down — after she went down.
The iceberg in question (1912) bore a streak of red paint on one side. Mocha Dick, the other big mythological white thing that used to sink ships (1839 ff), bore an unsually big number of barnacles all over him.
