Chaucer gave two early versions in English: "But all thing which that schyneth as the gold / Ne is no gold, as I have herd it told," and "Hyt is not al golde that glareth."
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 17th-century synonym for "glitters." The line comes from a secondary plot of the play, the puzzle of Portia's boxes (Act II - Scene VI - Prince of Morocco):

Young in limbs, in judgement old
Your answer had not been inscroll'd
Fare you well, your suit is cold.

"Not all that glitters is gold" is an alternative formulation.[5][6][7]

This is true of human beings also. There are many persons who seem to be good persons but they do many evil things. So, we cannot judge a man from his appearance. An innocent looking man may be a cheat. A man with a smile on his face may do some harm to us. A man, who says that he is our
