Laura Cumming, author of On Chapel Sands: My Mother and Other Missing Persons*, writes about this painting by Diego Velazquez which hangs in the Prado - "Las Meninas." (click to enlarge)
As I turned to look, all the people standing at the other end of the gallery suddenly moved aside as one, clearing an open view to the source of that light: Velázquez’s monumental Las Meninas. I had no thought of it, no idea it would be there or how vast it would be—an image the size of life, and fully as profound. The living people revealed the painted people behind them like actors in the same performance, and flashing up before me was the mirror-bright vision of a little princess, her young maidservants and the artist himself, all gathered in a pool of sunlight at the bottom of a great volume of shadow, an impending darkness that instantly sets the tenor of the scene. The moment you set eyes on them, you know that these beautiful children will die, that they are already dead and gone, and yet they live in the here and now of this moment, brief and bright as fireflies beneath the sepulchral gloom. And what keeps them here, what keeps them alive, or so the artist implies, is not just the painting but you.
You are here, you have appeared: that is the split-second revelation in their eyes, all these people looking back at you from their side of the room. The princess in her shimmering dress, the maids in their ribbons and bows, the tiny page and the tall, dark painter, the nun whose murmur is just fading away and the chamberlain silhouetted in the glowing doorway at the back: everyone registers your presence. They were here like guests at a surprise party waiting for your arrival and now you have entered the room—their room, not the real one around you—or so it mysteriously seems. The whole scene twinkles with expectation. That is the first sensation on the threshold of that gallery in the Prado where Las Meninas hangs: that you have walked into their world and become suddenly as present to them as they are to you.
The image holds you there, stopped in surprise, motionless as the moment it represents in which all these people pause too, except the little page nudging the stoic dog. Everything is still except for the circumambient air and the light fluttering across the white-blond hair of the princess, who stares at you with the candid curiosity of a child at the center of a painting that is itself so completely attentive. The dwarf gives you her frank consideration, hand on heart, the maids kneel or curtsy, the servants observe you, all the way to the man in black hovering on the threshold of this room, waiting to usher you into the next. And from behind the back of the great canvas on which he is working, the size of this one, steps the painter himself, taciturn, watchful, the magician momentarily revealed.
But take a few steps towards this painting in all its astounding veracity and the vision swithers. The princess’s lustrous hair begins to look like a mirage, or a heatwave scintillating above a summer road that vanishes at your approach. The face of the lady dwarf dissolves into illegible brushstrokes. The figures in the background become inchoate at point-blank range and you can no longer see where a hand stops and the tray it is holding begins. The nearer you get to the painting, the more these semblances of reality start to disappear, to the point where it is impossible to fathom how the image could have been made in the first place. Everything is on the verge of dissolution and yet so vividly present that the sunshine in the painting seems to float free and drift out into the gallery. It is the most spellbinding vision in art.
