All that glitters

 
The phrase 'All that glitters is not gold' is a very old one and means appearances can be deceptive.

I was taught that this was actually a misquote from Shakespeare who wrote 'All that glisters is not gold' in The Merchant of Venice (1596).

I recently heard that it was not a misquote since it appears even before Shakespeare's time as 'All that glitters is not gold' in Chaucer's Canterbury Tales (1387). However, upon checking I found that this was simply a modern translation and the original was worded:
But al thyng which that shineth as the gold
Nis nat gold, as that I have herd it told...

So we should be saying "All that glisters...", after all.
