[[File:Sonnambula atto 3.jpg|thumb|230px|Amina, the somnabuliste, at the mill]]
[[Vincenzo Bellini]]'s 1831 Italian [[opera semiseria]], ''[[La sonnambula]]'', the plot of which is centered on the question of the innocence of the betrothed and soon-to-be married Amina, who, upon having been discovered in the bedchamber of a stranger, and despite the assurances of that stranger that Amina was entirely innocent, has been rejected by her enraged fiancé, Elvino—who, then, decides to marry another. In fact, when stressed, Amina was susceptible to somnambulism; and had come to be in the stranger's bedchamber by sleep-walking along a high parapet (in full view of the opera's audience). Elvino, who later observes the (exhausted by all the fuss) Amina, sleep-walking across a very high, very unstable, and very rickety bridge at the local mill, realizes his mistake, abandons his plans of marriage to the other woman, and re-unites with Amina.

====Jenny Lind and James Braid====
In August 1847, the famous soprano [[Jenny Lind]] visited [[Manchester]], and gave two performances as Amina. The outstanding difference between Lind and her contemporaries was that, "whilst the beauty of her voice was far greater than any other in living memory (thus, the ''Swedish Nightingale''), what really set her apart was her outstanding ability to act"; and, moreover, in performing as Amina, rather than walking along a wide and well-protected walkway (as the others did), she routinely acrobatically balanced her way along narrow planks.<ref>[https://unsworks.unsw.edu.au/fapi/datastream/unsworks:11299/SOURCE01?view=true Yeates, L.B., ''James Braid: Surgeon, Gentleman Scientist, and Hypnotist'', Ph.D. Dissertation, School of History and Philosophy of Science, Faculty of Arts & Social Sciences, University of New South Wales, January 2013.] Yeates (2013), p.788.</ref>
