All that glitters is not gold

All that glitters is not gold
"All that glitters is not gold" is an aphorism stating that not everything that looks precious or true turns out to be so.
While early expressions of the idea are known from at least the 12th–13th century, the current saying is derived from a 16th-century line by William Shakespeare, "All that glisters is not gold".
Origins
The expression, in various forms, originated in or before the 12th century and may date back to Æsop.
The Latin is Non omne quod nitet aurum est. The French monk Alain de Lille wrote "Do not hold everything gold that shines like gold" in 1175.
Chaucer gave two early versions in English: "But al thyng which that shyneth as the gold / Nis nat gold, as that I have herd it told" in "The Canon's Yeoman's Tale", and "Hyt is not al golde that glareth" in "The House of Fame".
The popular form of the expression is a derivative of a line in William Shakespeare's play The Merchant of Venice, which employs the word "glisters," a 16th-century synonym for "glitters." The line comes from a secondary plot of the play, in the scroll inside the golden casket the puzzle of Portia's boxes (Act II – Scene VII – Prince of Morocco):
Glitters or glisters
The original version of the saying used the word glisters, though it is often taken as the similar and synonymous glitters. The poet John Dryden used glitter in his 1687 poem The Hind and the Panther.
Arthur Golding, in his 1577 English translation of John Calvin's sermons on the Epistle to the Ephesians, used the phrase "But al is not gold that glistereth" in sermon 15.
In 1747, Thomas Gray paraphrased the saying in his Ode on the Death of a Favourite Cat, Drowned in a Tub of Goldfishes which finishes with the lines:
In popular culture
Early uses
In H.M.S Pinafore, an 1878 comic opera by Gilbert and Sullivan, the phrase appears as "all that glitters is not gold."
In 1901, the sheet music publishers M. Witmark & Sons released "All That Glitters Is Not Gold", featuring words by George A. Norton and music by James W. Casey. The song is perhaps best remembered today for its inclusion in Bowery Bugs (1949), a Bugs Bunny cartoon based on the story of Steve Brodie.
Tolkien
The phrase is referenced with a reversal of the usual meaning in J. R. R. Tolkien's poem "The Riddle of Strider", originally written for The Fellowship of the Ring:
The poem emphasizes that sometimes gold is hidden or mistaken for something else, as opposed to gaudy facades being mistaken for real gold. Strider, secretly the rightful king of Gondor, appears to be a mere Ranger. Both Tolkien's phrase and the original ask the reader to look beneath the skin, rather than judging on outward appearance.
Popular music
Led Zeppelin reference the phrase in the opening line of their 1971 hit "Stairway to Heaven": "There's a lady who's sure all that glitters is gold". The song itself is filled with Tolkien references, perhaps referencing Tolkien's flipping of the phrase as much as the original itself.
Neil Young used the phrase in his song "Don't Be Denied" ("Well, all that glitters isn't gold/I know you've heard that story told"), from his 1973 album Time Fades Away, to express his "realization that even success wouldn't make him happy", even after he obtained fame and money.
In the 1973 single "Get Up, Stand Up" by The Wailers, Bob Marley and Peter Tosh used the phrase in the first verse to reflect the themes of the song - namely the critiques of colonialism and Christianity, and their roles in creating a feeling of resignation among the African diaspora contrary to their values and beliefs:
The song "Gold" by Prince has the refrain "All that glitters ain't gold".
A deviation from the phrase can be found in the song "Posthuman" by Marilyn Manson, released on the 1998 album Mechanical Animals, whose lyrics include the line "All that glitters is cold".
Rock band Smash Mouth used the version, "All that glitters is gold", in their 1999 song, "All Star."
