I am very often asked how was is possible that only a few contemporaries of Leonardo da Vinci knew of his relationship with the former Duchess of Milan, Isabella of Aragon. The answer is very simple. In the past we did not have the press of today. But even today we have to acknowledge that we have no idea what is happening in the House of Windsor behind closed doors. We know only what they are prepared to tell us. Here in Australia we have an actual case, where the NSW Premier Gladys Berejiklian had an intimate relationship with a colleague of her, Daryl Maguire, an acknowledged crook, for five years and only now we know about that. Although she was always surrounded by many journalists. Please, watch: Intimate secrets: Daryl Maguire reveals intimate relationship details with Gladys Berejiklian.
