theme-Don't jump to conclusion, listen before you act
plot- Due to Hera's unjustified anger and Narcissus's vanity Echo was cursed to only ever repeat what others said choosing to hide away in a cave till death, and Narcissus fell in love with his reflection losing interest in anything else starving to death
Beauty and the beast in my opinion has the most similarities to this story and teaches the most similar moral lesson of you should always listen before you act. Just like Hera Gaston was jumping to conclusions without giving what anyone said another thought. Theseus and the beast were so vain that it wound up getting the two of them both cursed, and Echo like Bell wound up in the cross fire of others problems.
Due to how strong he was and how all the woman adored him he became intent on making bell his wife without giving her any chances to express her own opinion.
however in the end Gaston got what he deserved, Bells love for the beast changed him back into the prince he once was. However the story of Echo and Narcissus is far different ending in the suffering inflicted on them by angry gods.
