This photo provided by The Metropolitan Museum of Art shows a watercolor on vellum by Jacob Marrel titled "Four Tulips: Boter man (Butter Man), Joncker (Nobleman), Grote geplumaceerde (The Great Plumed One), and Voorwint (With the Wind)" circa 1635–45. Highly detailed botanical illustrations might seem a thing of the past. But they continue to be made, commissioned, exhibited and published. And their enduring appeal can be important today for recording and focusing on nature under threat. (The Metropolitan Museum of Art via AP)
