The Portuguese poet Fernando Pessoa wrote that Newton's binomial theorem was as beautiful as the Venus de Milo.

I would like to add another masterpiece to the pair: Bach's Chromatic Fantasy and Fugue: [1]
I can't resist putting an alternative: Beethoven's last piano sonata: [2]
And yet another one (so beautiful that hurts, or maybe I'm becoming soft with age): Chopin's Étude in c-sharp minor: [3]
And also this sublime Agnus Dei from Bach's Mass in b minor (the boss, as Jebulon wrote: [4]
