Frothar or Frotar (Latin Frotharius, French Frotaire) was an Aquitanian prelate in West Francia, who held two different bishoprics and three abbacies during a long career.
[3] By maintaining control of the abbeys of Brioude and Beaulieu, he preserved his family's influence in southern Gaul during the ascendancy of the Marquis Bernard Plantapilosa.
[7] Rodulf and Frothar seem to have successfully negotiated the annulment and preserved peace between the two powerful Aquitanian families of Stephen and Raymond.
This was especially important because Aquitaine had recently been re-constituted as a subkingdom for the king's son, Charles the Younger.
[5] He also intervened with King Carloman II to have land in Fréjus in Provence taken from the abbey of Saint-Victor de Marseille returned to it.
