Rennie Alert!!! This week on NightVision--Hidden meanings and messages in Renaissance art with art expert Lisa Michelle. When high born families commissioned art, there was more to it than just requesting a pretty painting. Many messages and ideas, some profoundly heretical, were transmitted to those who knew how to 'see.' We'll have a look at some of those images and the find out what they were really conveying. We'll also hear about some of Lisa's work with the late grand master of the Rennes-le-Chateau mystery, Henry Lincoln. So, this is one not to miss!
