Metal to study...

[Billy]

As one writer put it when he described an artist looking at one of
Rodin's pieces, "perhaps he imagines what he would have done
differently, as that reaction is often a good artist's reaction to the
work of a master. They see not just the work, but how the work differs
from, and defines their own."

With this in mind, If you like working with metal, then there's an
exhibition of Bronze Casting at The Royal Academy till December the
9th. Some of the pieces are over 5000 years old!
