he art of time cannot escape this sine qua non of our existence. And since the dawn of horology, it has reminded us of it. One of the most famous examples is the watch in the shape of a skull that Mary Stuart, haunted by death, ordered in 1560, a time of religious wars, from the watchmaker Moyse of Blois. She wore it on a chain around her neck. But not for long, because in 1587, she was decapitated on the orders of Elizabeth I.
