L'argomento di questo articolo é il rapporto tra la cittá commerciale di Ancona e l'imperatore bizantino Manuel Komneno, espresso in una alleanza politico-militare durata dal 1155 al 1173. Si tenta di spiegare ció che una cittá italiana di media grandezza potesse rappresentare per Bisanzio nella sua ampia strategia di confronto con i Normanni di Sicilia e, piú tardi, con l'imperatore germanico Federico Barbarossa. I Bizantini non solo attribuirono grande importanza al loro simbolico « ritorno in Italia », ma usarono Ancona come base strategico-militare e come deposito di grandi quantitativi d'oro, col quale speravano di guadagnare alleati nell'Italia nord-rientale. Col miglioramento dei rapporti coi Normanni, Ancona non perse la sua importanza poiché era anche una leva contro i Veneziani, che Manuel Komneno vedeva con crescente ostilitá. La presenza di Costantino Donkas, dux della Dlmazia, ad Ancona nel 1173, sottolinea l'importanza che Ancona aveva in una piú ampia politica di espansione bizantina nell'Adriatico. Ancona, tuttavia, non fu posta sotto il governo diretto di Bisanzio, ma fu onorata dai Greci come cittá libera che era volontariamente entrata nell'orbita bizantina.

16 Strictly, it is not entirely clear whether Corfu was recovered as quickly as the Greek sources relate. Compare The Itinerary of Benjamin of Tudela, ed. Adler, M. N., (London, 1907), 10Google Scholar, with the propaganda of the court encomiasts: Mathieu, M., ‘La Sicile normande dans la poesie byzantine’, Bollettino del Centro di Studi filologici e linguistici siciliani, ii (1954), 1–28Google Scholar. Maybe Corfu was recaptured by the Sicilians in the 1150s. Lilie, Ralph-Johannes, Handel und Politik zwischen dem byzantinischen Reich und den italienischen Kommunen Venedig, Pisa und Genua in der Epoche der Komnenen und der Angeloi (1081–1204), (Amsterdam, 1984), 194–5Google Scholar, does, however, insist (on the basis of evidence from around 1200) that Corfu remained Byzantine; but some interruption cannot really be ruled out.

But whether there really were important Byzantine agents in Ancona on this occasion must remain doubtful; the δοῦξ of Dalmatia was in temporary retreat after a Hungarian advance into central Dalmatia, and it is uncertain who actually was δοῦξ in 1167: Ferluga, ‘La Dalmazia fra Bisanzio’, p. 77/207.

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.
112 My thanks are due to the Faculty of Archaeology, History and Letters of the British School at Rome for a grant in aid of research, which enabled me to make extensive use of the Vatican Library (and Archives) and the library of the German Historical Institute in Rome, as well as to visit Ancona.
