King William’s College, on the Isle of Man, has posted this year’s edition of “The World’s Most Difficult Quiz,” with its customary epigraph, Scire ubi aliquid invenire possis ea demum maxima pars eruditionis est (“The greatest part of knowledge is knowing where to find something”). Some sample questions:

• During 1925, in what was the worrying amnesia of Charles Edward Biffen revealed?
• Where did Ross’s trainer trial tendon-nicking on three sheep?
• Beating, tacking, reaching, luffing or even protesting — what took its name from the long-finned tuna?
• Which Roman edifice was believed to stand above the head of a mythical three-bodied ogre?
• Who was Mr Winterbottom?
• In which Cathedral is illumination seemingly provided by tungsten?
• What name mimicked that of an elite Pullman service, but with a change of weapon?
• Who warned of an explosion in three seconds on his banana night?
• Where was the final resting place of the Bronze Age toxophilite?

Answers will be posted at the end of January.

Usually MetaFilter organizes a Google spreadsheet of communal guesses; if that materializes I’ll post a link here.
