This picture is by the Hungarian artist István Orosz. It's of a French ambassador to England in 1530, his name is Jean de Dinteville. You might recognise Jean from the Holbein painting 'The Ambassadors' that we described on the Spy Blog recently.
Take a look at this vintage animation. Now try and follow the spiral around and around down into the middle. Not easy.
