In partibus Asie Maioris versus Mesopotamiam et Armeniam quidam Ionas vir venera bilis patriarcha erat in civitate Susis. In huius Ione manibus, dum missam celebraret more sue gentis ,hoc est secundum consuetudinem Surianorum, tale fertur accidisse miraculum, quod panis ille magnus fermentatus, unde fiebat sacrificium, in parvam et pulchram convertitur hostiam ad morem sacrificii Latinorum, et calix ligneus adnichilatur cum cochlearibus, recepto vero sanguine in argenteo calice; et hoc accidit in festo beati Iohannis baptiste huius anni, unde plures Surianorum ecclesie, Armenii, Georgiani, Lubiani, Nubiani et Iacobite ad consuetudinem sancte catholice et Romane ecclesie de die in diem per hoc miraculum ceperunt converti. Et iste Ionas patriarcha magno concilio Romano, de quo suo loco tractabitur, interfuit et postmodum in patriarcham Alexandrinum promotus est.
(In the parts of Asia Major in the direction of Mesopotamia and Armenia, was the patriarch of bile, a venerable man, in the city of Susis. While he was celebrating the custom of the mass of the nation, that is to say, according to the custom of the Syrians, a miracle by his own hands is said to have happened. The bread was in the most prosperous state of fermentation, from which an offering was made. The manner of the sacrifice was that the Latins received a small and beautiful host in which the blood was in a silver cup instead of a wooden cup without spoons. This is the case, and in the feast of blessed John the Baptist, of this year, the majority of the Syrian Church, the Armenians, Georgians, Lubians, Nubians, and the Jacobites, and the customs of the Holy Catholic and Roman Church, took the turn from day to day, by this miracle. And this is the great synod of decrees that Jonah was present, who was the patriarch of Rome, and was later promoted to be the Patriarch of Alexandria, of which we shall treat in its proper place.
