Using astronomical calculations and good old deductive reasoning, celestial sleuths provide the answer to a puzzle art historians have been trying to solve for years: the exact moment depicted in Vincent van Gogh's painting Moonrise. The answer: 9:08 p.m. local mean time on July 13, 1889.
In "Dating van Gogh's Moonrise," in the July 2003 issue of Sky & Telescope magazine, Donald W. Olson, a physics and astronomy professor at Southwest Texas State University, and his San Marcos colleagues Russell L. Doescher and Marilynn S. Olson reveal how they journeyed to Saint-Rémy-de-Provence, France, and solved the century-old mystery. Armed with topographic maps, aerial photographs, weather records, and letters written by van Gogh, the researchers were able to pinpoint the timing of the scene. Once thought to show the setting Sun at Saint-Rémy, it is now known to be a rendition of a rising Moon.
Throughout 2003, as special events commemorate the 150th anniversary of van Gogh's birth, there will also be an astronomical anniversary. Because of a cosmic synchronicity, the calendar dates of lunar phases in 2003 nearly repeat those of 1889. The 114 years since van Gogh's summer in Saint-Rémy correspond to six 19-year-long lunar Metonic cycles. Therefore, on this July 13th, modern observers during evening twilight will see a nearly full Moon rise in the southeast, much as it did on July 13, 1889, when van Gogh stood among the wheat stacks in a monastery field and captured the scene in his remarkable Moonrise.
