Lohengrin (Azione invisibile per solista, strumenti e voci) is an operatic monodrama by the Italian composer Salvatore Sciarrino.

[1] The opera, which is less than an hour long, is loosely based on Jules Laforgue's 1887 parody of Wagner's opera of the same name, published as part of his Moralités légendaires.

[2] The story of Sciarrino's Lohengrin is seen from the point of view of Elsa, a Vestal Virgin who is accused of fornication.

Eventually one of the pillows changes into a swan and Lohengrin returns to the moon on its back.

[1] The opera ends with the revelation that Elsa is actually a patient in a psychiatric ward.
