Origin of "all that glitters is not gold"

The origin of this idiom can be traced back to the late 12th century, when it was first used by the medieval monk and writer Geoffrey Chaucer in his work "The Canterbury Tales." In the story, a character refers to a false cleric as "a book that gleams like gold, but is actually made of lead." This was likely the earliest version of the phrase, which has evolved over time to become the commonly used idiom we know today.

The phrase gained popularity in the 16th century, with William Shakespeare using it in his play "The Merchant of Venice." It has since been used in various literary works, songs, and films, solidifying its place in the English language as a well-known idiom.

The origin of the idiom can also be traced to the idea of fool's gold, or pyrite, which is a mineral that resembles gold but holds no real value. This serves as a metaphor for things that may appear desirable or valuable, but are actually not as good as they seem.
