Jason Eskenazi (pictured top) knows how many figures there are in the Vanderlyn panorama. As a security guard at the Met, he spent three years at the museum bored out of his mind, “So bored,” he says, that he surveyed every inch of the 165-foot painting of the Versailles garden. “And so here’s the count,” he wrote in an essay, titled “Securitology and the Art of Boredom,” “403 people, 3 dogs, and 1 butterfly.” Mr. Eskenazi recorded this observation, along with many others, in a small Moleskin notebook he carried around in his back pocket. “Standing there all day, I needed to keep my mind going,” recalls the 51-year-old documentary photographer, who took the job as a guard after a Fulbright in Russia because he needed health insurance. In addition to the Fulbright, Eskenazi also received two Guggenheims, the Dorthea Lange prize, and countless others awards before beginning at the Met as a guard.
