This series of free podcasts about the Uffizi Gallery in Florence was designed with young viewers in mind, but should be handy for adults too. Please note: these podcasts date to 2008. You might want to buy my Uffizi Art History Guide for IOS instead.
Start with the Introduction to the Uffizi. This is the Second Part – the Giotto Room, which is a presentation of the first room you enter off the hallway. This room features a large enthroned Madonna by Giotto in the center, and similar shaped works by Duccio and Cimabue. The podcast compares these works which might at first look similar to you. What we have here is actually the Tuscan Proto-Renaissance, and the small distinctions between the works show a move towards a more naturalistic style.Click play to hear the podcast!
