A.A. Merritt and H.P. Lovecraft were frequent visitors of Roerich’s while he was in New York. Although Lovecraft never went to Asia himself, he seems to have traveled vicariously through Roerich.
“Better than the surrealists, though, is good old Nick Roerich, whose joint at Riverside Drive and 103rd Street is one of my shrines in the pest zone. There is something in his handling of perspective and atmosphere which to me suggests other dimensions and alien orders of being—or at least, the gateways leading to such.
