Diego Velasquez' "Las Meninas"
In the recent Aug/Sept 2015 issue of History published by National Geographic, a two-page article was written on the subject.
In a sidebar in the article, this question was asked, "Are (the Royal Couple depicted in the mirror in the background) spectators of the mastepiece or reflections from the hidden canvas?"
I had a problem with author Tania Levy's question as it seemed to limit to an either/or, when another possibility exists.
The Royal Couple was the subject of the hidden canvas being painted by the self-portrait Diego Velasquez. Instead of the hidden canvas being reflected in the mirror, it is their 'actual' imagery being reflected. Since they were posing for the painting, they could hardly be called spectators.
Diego's brilliance is in putting what is seen by the Royal Couple, while posing, onto the canvas.
Can one imagine such an exercise in Drawing 101? Instead of drawing an apple, a vase, or a partially nude poser, one is drawing what the subject might be seeing.
I thank Ms. Levy and National Geographic for the article.
