From 1748 onwards, the marvellous made a comeback in opera seria via the Königliches Opernhaus in Berlin. The striking resurgence of myth and magic in the predominantly historical operatic genre appears to bespeak a growing interest in Lullian tragédie en musique, which in turn can be associated with Frederick II's French orientation in literary and philosophical matters. But how did deities, sorcerers and Louis quatorzien imports chime with Frederick's notorious resistance to superstition and divinely ordained kingship? The juxtaposition of the relevant operas with theoretical writings from Friderician Prussia yields a multi-faceted, somewhat paradoxical answer, revealing that the marvellous, alongside nourishing a new type of operatic spectacle, served Frederick as a vehicle to impart his philosophical agenda to his state, a former centre of Pietism.

Two King's Bench lawsuits in The National Archives of the UK contain new information about the activities of castrati working in mid-eighteenth-century London. Monticelli v. Sackville (1748) confirms Horace Walpole's testimony that singers employed by the Earl of Middlesex's opera company received enormous salaries. Manfredini v. Geminiani (1751) preserves details of a contract of employment between singer and impresario that went disastrously wrong for both parties. An account of the London careers of the main protagonists is supplied to contextualise the new information.

Die Frau ohne Schatten (The Woman without a Shadow, 1917) was conceived as Richard Strauss and Hugo von Hofmannsthal's ‘chief joint work’, and its central message has been read as an allegory of artistic collaboration and social engagement. This article calls upon Walter Benjamin's theory of allegory to enrich such an interpretation and unravel the opera's positive conclusion as an inadequate cure for the artistic melancholy of the fin de siècle. While Strauss successfully engaged with allegory to portray two of the opera's characters – the infertile Emperor and Empress – he was unable, for his own philosophical reasons expressed in the contemporaneous Eine Alpensinfonie (1915), to ratify Hofmannsthal's hope, rooted in his ‘Chandos Crisis’, of creating an aesthetic totality, of reconstituting the symbol that Benjamin, in his later writings, pits against allegory.

The preparation of the critical edition of Verdi's I due Foscari has drawn attention to two overlooked sources: an early scenario attributed to Andrea Maffei and an early manuscript copy with various layers of corrections. This article questions the scenario's attribution to Maffei, revising the opera's early history. It furthermore identifies one of the layers in the manuscript copy as being in Verdi's hand, showing that the composer's role in fine-tuning a libretto at this early stage in his career was greater than has so far been possible to show.
