Andrew Lang’s Custom and Myth, published in the late 19th century, explores the universal yet culturally diverse origins of folklore, myth, and religious belief. Drawing on examples from Greek, Australian, and Finnish traditions—such as the Kalevala and references to Cronus—the work examines how ancient myths, rooted in totemism and kinship, persist beneath layers of civilization. Lang analyses the interplay between elemental beliefs and evolving faiths, noting how even Christian societies retain traces of older mythologies.
His synthesis of global narratives, from the "cruel, puerile" tales of indigenous peoples to the poetic harmony of nature in myth, underscores the enduring human impulse to personify the cosmos. By tracing parallels between seemingly disparate cultures, Lang argues that mythological evolution reflects both universal human traits and the unique imprint of each society’s "race" on its stories.
