Giotto has been considered the father of modern painting But anewly discovered fresco by Pietro Cavallini in Rome could rewrite the arts history books. “The crucial thing is to determine whether it was done before 1288, when work began in Assisi on the Cycle of St Francis, or after. If it was before, it means that it was Cavallini who was the master, and thus the father of modern painting. If it was painted afterwards, then it will still go down as a beautiful and very important work of art to be discovered – but nothing more.” – The Telegraph (UK)
