what tools micheal angelo used on his art work the etruscan?

Answer 1

We have a bit of a problem here. One assumes that Michelangelo used alone refers to the Renaisance painter and sculptor. But since there is no connection made in Google with The Etruscan, we look a little further and find that
"The Etruscan," a sculpture by Michelangelo Pistoletto an artist born in 1933
http://www.guggenheimcollection.org/site/artist_bio_128.html
has produced a work which is one of my favorites in the Ft.Worth Modern which has a bronze statue looking in a mirror. I had always assumed the statue was adopted from some other source, but maybe not.

The statue in The Etruscan is a bronze which means it was worked up in clay and wax and then cast by the lost wax method.
