¹¹¹ Buoncompagno, 34, implies that Ancona was a ‘feudum’ of Manuel Komnenos, but he introduces the link between Ancona and Constantinople in an oblique way—his prime aim is to introduce Constantine Doukas, and place some fine words in his mouth. In the nineteenth century the siege of Ancona (then dated to 1174 rather than 1173) was the subject of a number of romantic works: Cannonieri, G., L'assedio di Ancona dell'anno 1174 per Cristiano arcivescovo di Magonza, luogotenente di Barbarossa (Florence, 1848Google Scholar), has what purports to be a ‘Conclusione Storica’ by F. Soragni (pp. 225–40); cf. Giangiacomi, 396 and 403–4 for a similar work. Cannonieri's work reads as a bad pastiche of Manzoni; its fantastic tale of Guglielmo Gosia and his beloved Virginia is, alas, without any historical foundation.
