Alex Reid Painting T-shirt?

[lea27]

The other day Alex was wearing a t-shirt that depicts someone dressed as a Greek or Roman God, like Mars and around him are his current family also seen as Gods. The person is someone else from history like a king and his family but being shown in the Classical style, I think the painting itsellf is like 16th century. I've seen the actual painting somewhere else and just cant think who it depicts??
