The painting of the ambassadors by Hans Holbein has a mysterious, menacing skull set slantwise on the bottom of the famous painting, which is now rightfully placed in the National Gallery-London. Many people would think 'Why is that there?' or 'There is absolutely no point in putting that there!' but there actually is. This skull represents that one day, everyone has to die; unfortunately for this picture, it has to bare a skull, as it makes it look creepy. Would you have put this terrible act of death inside your painting?
