California, the Golden State, has long drawn artists to her shores, mountains, and valleys. The lure of a varied—yet near perfect—climate and the resulting light was irresistible to, among the many others, Arthur G. Rider (1886-1975). Rider settled in southern California in 1931 and remained for the rest of his life. There Rider discovered the same type of natural beauty he experienced in Valencia, Spain, when he was the protégé of Joaquín Sorolla y Bastida (JAMA cover, February 17, 2010). Sorolla, most famous for his depictions of the sea and the sands of the central eastern Spanish coast, painted in an Impressionist manner; he was a pintor de la luz, a painter of light. Rider's canvases, including The Spanish Boat (cover), summon the specter of the Iberian master in their resemblance, yet the paintings bubble over with Rider's particular panache.
