Sculptor Giovanni Strazza probably completed this bust of a veiled Virgin Mary in the early 1850s. It was transported to Newfoundland and placed in the Episcopal Palace next to St. John’s Basilica.

“To say that this representation surpasses in perfection of art, any piece of sculpture we have ever seen, conveys but weakly our impression of its exquisite beauty,” wrote a local newspaper. “The possibility of such a triumph of the chisel had not before entered into our conception. Ordinary language must ever fail to do justice to a subject like this — to the rare artistic skill, and to the emotions it produces in the beholder.”

In 1919, engineer James Cowan Smith bequeathed £55,000 to the National Gallery of Scotland.

He set two conditions. One was that the gallery provide for his dog Fury.

The other was that this picture of his previous dog Callum, by painter John Emms, always be hung in the gallery.

Both conditions were fulfilled.

Robert Doisneau’s iconic photograph of young love in Paris sold thousands of posters, but the identity of the couple remained a mystery for decades. In 1988 Jean-Louis and Denise Lavergne saw it on a magazine cover and thought they recognized themselves: They’d been on the rue de Rivoli on April 1, 1950, and had a diary to prove it, and Lavergne still had the skirt and jacket she’d worn that day. They contacted Doisneau, who greeted them warmly but did not offer to share any of the five-figure income he’d been making each year from the poster.

When they sued him, he revealed that he’d posed the shot using Françoise Delbart and Jacques Carteaud, a couple he’d seen kissing in the street but had not dared at first to photograph. Finally he’d approached them and asked them to repeat the kiss. Delbart said, “He told us we were charming, and asked if we could kiss again for the camera. We didn’t mind. We were used to kissing.”

A thousand bubbles burst, the Lavergnes lost their suit, and Delbart eventually sold the print Doisneau had given her to feign a spontaneous kiss. She didn’t share the proceeds with Carteaud — they’d broken up nine months after the photo was taken.

What is Chopin’s B Minor Sonata? What constitutes its identity? Not the fact that it’s part of Chopin’s conscious experience, because it continues to exist after his death. And not the fact that it’s part of any listener’s experience, because it continues to exist when those experiences have ended. It can’t be identified with any particular performance, and it’s different from its score, since the sonata is a sounding work and the score is an arrangement of graphic signs.

If the sonata is not material, and if it’s different from the experience of both the composer and the listener (in fact, it continues to exist if no one takes any conscious interest in it at all), how can it exist? How do we discern the same “original” work in a hundred different performances?

Is the sonata an ideal object, immutable and atemporal, like a mathematical concept? Well, no, because Chopin created it at a particular time. Perhaps there is no sonata, only individual performances? But then there’d be no sense in distinguishing a performance from the work itself, or in talking about the identity of a work (“Chopin’s B Minor Sonata”), or in arguing over whether a given performance was faithful to the original.

“For what is the point of saying that one performance rather than another gives a more nearly accurate account of the B Minor Sonata when the sonata does not in fact exist and when there is nothing real with which these performances may be compared?” asks philosopher Roman Ingarden. “Are we really going to agree that such judgments concerning the sonata itself and its performances are all false and stupid?”

M.C. Escher hated the Dutch high school he attended between 1912 and 1918. He failed his exam and enjoyed only the drawing lessons. But now it appears that the school’s architecture informs some of his later prints.

“It recently became clear that the staircase in Escher’s secondary school was a crucial factor in several of his works,” writes Micky Piller, curator of the The Hague Escher Museum, in The Amazing World of M.C. Escher (2015). “This discovery was confirmed by analysis of this work and photographs taken in the school.

“Escher was an unhappy boy when he was going up and down this staircase. Thirty years on, he still described his school years as ‘the hell that was Arnhem.’ Here he would have seen pupils walking in every direction. Imagine this in your mind’s eye and you will understand the rotating perspective in the print.”

“It was not all imagination, we must conclude now.”
