Masaccio (, , ; December 21, 1401 – summer 1428), born Tommaso di Ser Giovanni di Simone, was a famous painter of the Italian Renaissance. He worked in Florence. "Masaccio" was a nickname that meant "Fat Untidy Tom". He lived a very short life and only a few of his paintings exist, but they were so different to the style of other artists around him that they helped other painters to see things in a new way.
