Pearl resists identification by author, date, occasion, or place of composition; still it is almost unanimously hailed as one of the masterpieces of our literature, so skilled is its author, so eloquent its language. It is a story, according to Sarah Stanbury, "of crossing-over, the stepping out from the ordinary life into a parallel universe where things operate by different natural laws: down the rabbit hole, through the wardrobe or looking glass, across the ocean to be shipwrecked on Prospero's island, or more recently, across a bridge to the island of Willow Springs in Gloria Naylor's haunting novel, Mama Day, where the crossing-over moves into a place of memory and hope, the nostalgic space of home as well as Beulah or Eden, the earthly paradise."
