This letter, penned by
Odo of Rheims, describes the arrival to Rome of a Byzantine retinue escorting a nameless Indian Archbishop who described to an audience including
Pope Calixtus II the marvels that occur in his country through the ghostly power of
St. Thomas. Odo claims to have witnessed this meeting.
From Silverberg (p. 32):
“Odo, who lived from 1118 and 1151, probably wrote the letter between 1126 and 1135. In it he tells of being present at the court of the Pope when a delegation of ambassadors form Byzantium arrived, bringing with them a certain Archbishop of India, whom Odo does not name… He declares that the ruler of the archbishop’s country had died, leaving no heir, and the archbishop had gone to Byzantium to obtain a new prince for his land from among the Byzantine emperor’s entourage. Twice the monarch had received the archbishop graciously and had nominated one of his courtiers to the Indian throne, but each time the designated candidate had perished en route to India. The emperor had declined to select a third; but instead of setting out immediately for his homeland, the archbishop had gained permission to visit Rome in the company of the Byzantine ambassadors… Odo relates that the Pope and his cardinals refused to believe these tales until the archbishop swore an oath that convinced them”
The events in this text largely mirror those described in the
de Adventu, with some key differences. For one, Odo claims that Patriarch John arrived with a Byzantine retinue while the
de Adventu asserts that John arrived with a group of returning papal legates. In another example, Odo records that it is a river that prevents access to the mountain that houses the magical shrine of St. Thomas, rather than the lake
de Adventu suggests. Though a minor discrepancy, the motif of rivers is
bountiful in Prester John lore.
From Slessarev (p. 12):
“The greatest deviation from De adventu occurs, however, in the explanation of the causes of the Patriarch’s trip to Constantinople. According to Odo, the prince of the country, friendly helper of the archbishop, had suddenly died. This misfortune compelled the prelate to go to the emperor at Byzantium and beg him for another prince. The Greek monarch received him graciously and provided him twice with a suitable candidate from his immediate entourage, but in both cases, for no reason stated, the courtiers died while en route to India.”
