The 20th-century painter Balthus once suggested that the author of a book about him began with the words: ‘Balthus is an artist about whom we know nothing; now let’s look at his works.’Actually, there are many important figures about whom we know nothing, or at least very little. Giovanni Bellini is a case in point. Information we don’t have about him includes when he was born, and even whether he was the younger sibling of Gentile Bellini — as is usually assumed — or in fact his uncle.
