Spiritualism has seen a rise in popularity in the art world in recent years, as artists from throughout the last century enjoy new-found interest. Now, the Gallery of Everything in London is exploring the nature of spiritualism in art at its physical space—in a new exhibition titled Medium’s Medium—and a special booth at Frieze Masters. “The advent of spiritualist art-making in the 19th and early 20th century is emerging as an important addition to the art historical canon,” says the gallery. “For many years, the strange scribblings, obscure symmetries, figurative imaginings and floral bouquets transmitted from so-called other worlds, were overlooked—even ignored—by the cultural mainstream.”
