The Comtessa de Dia, possibly named Beatritz or Isoarda, was a trobairitz. She is only known as the comtessa de Dia in contemporary documents, but was most likely the daughter of Count Isoard II of Diá. According to her vida, she was married to William of Poitiers, but was in love with and sang about Raimbaut of Orange. Bruckner, Shepard, and White cite Angela Rieger's analysis of the songs, which associates them, through intertextual evidence, with the circle of poets composed ofRaimbaut d'Aurenga, Bernart de Ventadorn, and Azalais de Porcairagues. Marcelle Thiébaux, and Claude Marks have associated her not with Raimbaut d'Aurenga but with his nephew or great nephew of the same name. If her songs are addressed to Raimbaut d'Aurenga's nephew Raimbaut IV, the Comtessa de Dia may have been urging the latter to support Raymond V of Toulouse. It has also been hypothesised that the Comtessa de Dia was in fact married to Guillem's son, Ademar de Peiteus, whose wife's name was Philippa de Fay, and that her real lover was Raimbaut de Vaqueiras. Beatrice's poems were often set to the music of a flute. Five of her works survive, including 4 cansos and 1 tenson. Scholars have debated whether or not Comtessa authored Amics, en greu consirier, a tenso typically attributed to Raimbaut d'Aurenga. One reason for this is the similarities between this composition and her own Estat ai en greu consirier. A second reason references the words in her vida, Et enamoret se d'En Rambaut d' Aurenga, e fez de lui mantas bonas cansos. A tenso between Giraut de Bornelh and Alamanda de Castelnau closely matches the structure of A chantar m'er de so qu'ieu non volria. The phrase in it, vestida ni nuda echoes en lieig e quand sui vestida in Estat ai en greu cossirier. The tenso may have been composed as a response to these songs. Her song A chantar m'er de so qu'eu no volria in the Occitan language is the only canso by a trobairitz to survive with its music intact. The music to A chantar is found only in Le manuscript di roi, a collection of songs copied around 1270 for Charles of Anjou, the brother of Louis IX. Her extant poems are: Typical subject matter used by Comtessa de Dia in her lyrics includes optimism, praise of herself and her love, as well as betrayal. In A chantar, Comtessa plays the part of a betrayed lover, and despite the fact she has been betrayed, continues to defend and praise herself. In Fin ioi me don'alegranssa, however, Comtessa makes fun of the lausengier, a person known for gossiping, comparing those who gossip to a "cloud that obscures the sun." In writing style, Comtessa uses a process known as coblas singulars in A chantar, repeating the same rhyme scheme in each strophe, but changing the a rhyme each time. Ab ioi, on the other hand, uses coblas doblas, with a rhyme scheme of ab' ab' b' aab'. A chantar uses some of the motifs of Idyll II of Theocritus.
