King James II of England, when he saw the restored and expanded St. Paul's Cathedral, called it "amusing, awful and artificial." The architect, Sir Christopher Wren, was not offended. On the contrary, he was flattered.
The king did not mean that it was funny or entertaining. He was not calling it atrocious or appalling. He did not consider it fake or pretentious.
In 17th century England, amusing meant "riveting." Awful meant "full of awe" or "awe inspiring." And artificial meant "artistic."
(Interestingly, "literally" has been misused to mean its opposite since at least the 1680s: http://www.etymonline.com/index.php?term=literally&allow... . We've held off the "it means just what I choose it to mean" hordes so far, why give up now?)
I got curious so I looked up some examples that still can mean something or the exact opposite:
Bolt - run away or secure in place
Cleave - cut or join
Garnish - add (parsley) or remove (wages)
Weather - weather the storm or become weathered
