It was much harder to take a "selfie" in the 16th century than it is today. There were no smart or even dumb phones. Photography didn't yet exist. If you wanted a keepsake image of yourself or a snapshot of your lover, you had to find and commission an artist to paint one. Which meant (among other things) that you had to be rich.
The albums in which a precious few such pictures have been preserved are called museums, and Frederick Wiseman's superb documentary about them is called "National Gallery" - the London one.
