Ballet in three acts with choreography and libretto by Bournonville, music by H. S. Paulli, E. Helsted, N. W. Gade, and H. Lumbye, and design by C. F. Christensen. Premiered 29 Mar. 1842 by the Royal Danish Ballet in Copenhagen with Bournonville, Caroline Fjeldsted, and Füssel. One of the most popular of all Danish ballets, it tells the story of Teresina, bride-to-be of the Neapolitan fisherman Gennaro, who is swept overboard in a storm, saved by the sea-sprite Golfo and spirited away to a grotto on the Island of Capri where Golfo turns her into a naiad. Gennaro tracks her down and breaks the spell and the exuberant third act celebrates their wedding. It is usually only the third act, with its lively divertissements (mainly credited to Hans Beck), which is now performed. However, the full-length ballet is still in the repertoire of the Royal Danish Ballet and was given a new staging in 2009 by Nikolaj Hubbe, with a new second act (chor. Hubbe, mus. Louise Alenius Boserup) and a 1950s' setting. Peter Schaufuss staged a full-length production for the National Ballet of Canada in 1981 and for English National Ballet in 1989. Its first full production by a British company was P. Gnatt's staging for Scottish Ballet in 1978. The Act III divertissements entered the repertoire of the Royal Ballet in 1962 staged by Bruhn, and again in 2007, staged by Kobborg, and have also been danced by American Ballet Theatre in a 1974 staging by H. Brenaa.
