Harlequin Cock Robin and Jenny Wren; or, Fortunatus and the Water of Life, the Three Bears, the Three Gifts, the Three Wishes, and the Little Man who Woo'd the Little Maid[1] was a pantomime written by W. S. Gilbert. As with many pantomimes of the Victorian era, the piece consisted of a story involving evil spirits, young lovers and "transformation" scenes, followed by a harlequinade.
The piece premiered at the Lyceum Theatre, London on 26 December 1867. It was the only pantomime written by Gilbert alone, although before and afterwards he collaborated with other authors on pantomimes for the London stage. It was written early in his career, when he was not yet an established playwright, and the script was regarded as of less importance than the spectacle. The first night was under-rehearsed, and the spectacular effects and scenery failed to work properly. Later performances were satisfactory in that respect, and the piece received some good reviews.
