Princes are thin on the ground these days. While there are still a few royals reigning across Europe, the world of interrelated international royalty that evoked a glittering combination of Grimm’s fairy tales and Ruritania is long dead everywhere except Netflix Christmas movies. But there’s one person left who’s a living connection to the milieu of European monarchy: Prince Philip, Duke of Edinburgh, who will turn 100 years old in June and is currently in the hospital. Buckingham Palace informed media that after a two-week stay at London’s King Edward VII Hospital, he’s been moved to Bartholomew’s Hospital for further treatment of a stubborn infection and a “preexisting heart condition,” but that it’s responding to treatment and he “remains comfortable.”
