English: Illustration of the Battle of Yarmouk (636) at the bottom of the page of BNF Nouvelle acquisition française 886 fol. 9v (early 14th century). The Saracens are shown with a star and crescent banner, the Byzantines (anachronistically in Crusader era armour) with a star banner. Note that the banner designs are not attributed to factions with any consistency by this illustrator: The star and crescent is also shown as carried by the Mongols in foll. 22r, 32v, 34r, 35v). For a later (mid 14th-century) copy with more developed heraldry, see Vienna ÖNB Cod. 2623 [1] fol. 15r.

Hayton's (Faulcon's) text reads:

Lors manda l'empereour Eracles grant secors de genz pour defendre la cité d'Antioche. Qant les genz de l'empereour Eracles furent parvenuz jusques à une plainure qui est nomée Possent (var.: Posserit), les Sarazins vindrent à l'encontre; e là fu comencée molt grant bataille que longuement dura; mès, à la fin, les Sarazins en orent la victoire, e tant gent furent ocis en cele bataille que encores y perent les ossements des seignors en celui champ. Dont il avint que les Grex, qui tenoient la cité d'Antioche, furent molt espoentés, e rendirent la terre as Sarazins par convenances. ( La Flor des Estories de la Terre d'Orient II.1, ed. Dardel 1906, p. 137 .)
