Rostang of Arles

Around 875 the new Duke of Provence, Boso, seized the property of the Reims church in Provence. These areas, called "Civitis Fretus", have been identified with the current territory of Saint-Rémy-de-Provence, north of Arles. The Archbishop of Reims, Hincmar, turned to Rostang for protection, as 12 years earlier he had requested assistance from the previous Archbishop of Arles, Rotland.[2]

Rostang attended the Council of Pontigni in 876 which ratified the resolutions of the Council of Pavia concerning the coronation of Charles the Bald.[3] In the spring of 878 Pope John VIII, threatened in Italy, came to look for allies on the other side of the Alps. He was welcomed in Arles by Boso, the Duke of Provence, and Rostang who received the pallium. Pope John VIII declared the Arles prelate vicar general in France and enjoined all bishops to obey him.

Rostang attended several councils, including that of Mantaille in 879, where Boso was crowned King of Provence. He was one of the minority Provençal bishops who vote for the election of Boso. Indeed, only it seems four prelates out of twenty-three (including eleven present) supported this takeover.[4] It underlined the strong commitment at that time of the Arles episcopate to the Burgundian princes. Boso, barely crowned, showed himself in the provinces that had just submitted to his kingdom. He then confirmed, in favor of Archbishop Rostang, the charters by which the emperor Lothaire and his son, his predecessors, had submitted Cruas Abbey in the Vivarais to his church. The monks of this monastery, to prevent schemes of the bishops of the country, had themselves asked these princes to give them the archbishops of Arles as protectors.[1] A charter, the sixth and last of Boso, dated 886 or very early 887, at the request of the Archbishop of Arles reassigns the jurisdiction of Cruas Abbey to Rostaing.[5]

But from the end of the 870s, the city of Arles was exposed to the blows of the Norman and Saracen pirates who ravaged the delta. Saint-Césaire Abbey was sacked and then abandoned. It was not until 883 that it was restored by Rostang. Subsequently, in his will of June 6, 897 the archbishop returned looted property to the monastery.[6] This allowed the resumption of conventual life, and the abbey became an important ecclesiastical lordship of the Arles region.

Shortly after Boso's death, Rostang took part in the Council of Nîmes of 888,.[7][lower-alpha 1] This council was chaired by Theodard, Archbishop of Narbonne, and not by Rostang.[8]

Rostang took an active part in 890 in the meeting in Valence which organized a kingdom of Provence around King Louis the Blind, Boso's son.

In 901 or 902, he presided in the Narbonne region over the council of Azillan concerning a dispute of jurisdiction between the deacon Thierry and the priest Tetbald. He was assisted by Arnuste, archbishop of Narbonne[9] In 909, he gave the Church of Apt the villa of Fastignane and its vineyards located at the confluence of the Calavon and the Dôa.[10] He is mentioned in 911 about the appointment of Gérard, Bishop of Narbonne, where he intervened with the Bishop of Uzès, Amélius II.[lower-alpha 2] The Gallia christiana novissima estimates that this episode takes place around 913.[11] This would be during the civil war which was ongoing in the South. It gives some details: after the assassination of Arnuste[lower-alpha 3] the archbishop of Narbonne, the clergy and the people sought advice from Rostang who went to Agde with Amèle (Amélius) bishop of Uzès. Rostang elected Gérard, Amèle's nephew. He then went to Narbonne to put Gérard in possession of his archiepiscopate against Agio, who was appointed in the meantime by the bishops of the Province.[12] It was during the reign of Louis, between 890 and 910, that the mint of Arles was given by the king to Rostang.[13]

It is believed that Rostang died in 913. The see of Arles remained vacant for a year, after which, Pons, bishop of Orange, was appointed to fill it; but did not take possession.[14] However, the Gallia christiana novissima refers to an undated document, but according to it from January 920, in which decisions of the Archbishop are reported.[15]
