Non vorrei entrare in un campo minato , ma con buona pace di draghi , principesse
ed altre fantastiche creature
, pare storicamente accertato che l’aquila bicipite oro in campo rosso sia di origine bizantina .
Per ipotizzare l’origine dell’aquila oro in campo rosso ed eventuali variazioni, negli stemmi italiani ( vedi mio avatar ) avevo raccolto qualche documento che vi propongo :
Una suggestiva ipotesi riportata dal Bellarmino racconta che l’aquila a due teste ebbe origine dalla divisione dell’impero fatta da Arcadio ed Onorio, figli di Teodosio (…). L’impero d’Oriente è rappresentato dall’aquila d’oro in campo rosso; l’impero d’Occidente dell’aquila nera in campo d’oro.
Con il seguente contributo , sembrano diradarsi le nebbie che avvolgono le figure che appaiono negli stemmi Giustiniani delle Venezie : L’ANGELO e L’AQUILA BICIPITE ORO IN CAMPO ROSSO
A conforto delle affermazioni di San Marco , sull’origine bizantina della famiglia Giustiniani.

Two particular insignia have attracted a lot of attention, namely the double-headed eagle and the "tetragrammatic cross" (cross between 4 B's).
First, the eagle: it appears as a decorative motif at the court of the last Comnenoi and the Ange family (12th c.), on the cermonial costumes of members of the imperial family but not on the emperor himself. The same is true of the courtt of the Laskaris in the empire of Nicea (1204-61). The Crusaders have used the double-headed eagle as symbol of the empire, although the arms of the empire itself were: Gules, a cross between four crosslets or inscribed in an annulet each and between four crosslets each, all or. The double-headed eagle was taken back to Western Europe by two daughters of the first Latin emperor, one who struck coins in Flanders with the eagle, the other marrying into the house of Savoy and bringing the eagle in the Savoy achievement.
Even after the restoration of the empire and the Paleologue emperors, the eagle is still used by the imperial family but not the emperor. The first known use is in 1301. In the 14th c. the Paleologues used either a single-headed or double-headed eagle as emblem, settling on the double-headed eagle in the 15th c. But it always remained outside of the shield. The exceptions occur in Western documents: Ulrich von Richental's Conciliumbuch describing the arms of the participants in the Constanz council of 1414-18 is one. As for the other, in August 1439 John VIII Palaiologos conferred upon Giacomo de Morellis, a citizen of Florence, the right to place on his banner the imperial blazon (semeion); a painted representation of a shield gules with a double-headed eagle or on the document is probably a posterior addition. Thus the eagle was probably never thought of as a charge, which explains the tradition of the former imperial families (as well as states such as Serbia) of placing their arms on an escutcheon on the breast of the eagle.
As for the tetragrammatic cross, even though it was considered at the time by some to be the arms of the Paleologue family, it was in fact the arms of the Byzantine empire. The motif of a croos between four objects is derived from Constantine's labarum and has long figured on Byzantine coins, since the 6th c.
Arms of Some Byzantine Families
These arms all come from Rietstap. The Angelos, Cantacuzene, Comnene, Ducas, Lascaris, Paleologue, Vatatzes families held the imperial throne at some point, and all but one display a double-headed eagle. A branch of the Paleologue family ruled over Montferrat in Northern Italy, when the title passed to the Gonzaga family (who quartered their arms with Paleologue); the latter died out in the early 18th century. As for the Comnene, they were still living in Corsica at the time of the French Revolution.
