St. Francis, Giotto and Geology

St. Francis of Assisi (c.1181-1226) and Giotto (c.1270-1337), would change the history of religion, art and ecology. Some 800 years later, geologists would examine the limestone used to construct the Basilica of St. Francis at Assisi and would discover the secret behind the extinction of the dinosaurs.
