What do these three pictures have in common?

The first is the bust of Nefertiti, an Egyptian queen. The bust is now in the Neues Museum in Berlin and is one of the most beautiful works of art. *Nefertiti* is translated as “a beautiful woman has come”. The word *nefer* is in this case translated as ‘beautiful’.

The second is a drawing of a Grecian urn by Keats. Keats’ *Ode on a Grecian Urn* ends with the line “Beauty is truth, truth beauty,”.

The third picture is part of the Moscow Mathematical Papyrus from ancient Egypt.
