The Sámi minority retained their shamanistic religion well into the 18th century, when most converted to Christianity under the influence of Dano-Norwegian Lutheran missionaries. Although some insist that "indigenous Sámi religion had effectively been eradicated,' anthropologist Gutorm Gjessing's ''Changing Lapps'' (1954) argues that the Sámi's "were outwardly and to all practical purposes converted to Christianity, but at the subconscious and unconscious level, the shamistic frenzy survived, more or less latent, only awaiting the necessary stimulus to break out into the open." Today there is a renewed appreciation for the Sámi traditional way of life, which has led to a revival of ''Noaidevuohta''. Some Norwegian and Sámi celebrities are reported to visit shamans for guidance.
