Countess of Barcelona and Septimania, she is considered to be the first female writer of the 9th century. Born into a noble Carolingian family around 803, she was married to Bernat de Septimania, the Count of Barcelona. In 826, after the birth of her first child, the Count sent her to the Chateau de Uzés, in France, a forced exile from which she never returned. Alone and separated from her family, she learned to govern the lands of her husband, who visited her and with whom she had two more children, who were also separated from their mother using political and military arguments. Around 841, she wrote a manual of religious, moral and practical advice for her son Guillem, who was 16 years old: Liber manualis, a copy of which is currently conserved in the Library of Catalonia. The Besòs-Mar metro stop is close to Carrer de Duoda.
