Timbor of Rocabertí

Timbor of Rocabertí (1318–1364) was a Catalan noblewoman who sided with Sardinia against her own countrymen. Daughter of Viscount Dalmau VII of Rocabertí, she married Marianus of Arborea in 1336 at the Aragonese court in Barcelona; the couple lived at Molins de Rei, where Hugh III and Eleanor of Arborea were born.

When Marianus became judge in 1347 she moved to Oristano and backed his war against Aragon without reserve. He often made her regent during campaigns and sent her as ambassadress, and at Alghero she mediated with her kinsman, the Aragonese admiral Bernat de Cabrera.

She gave generously to the monastery of Santa Chiara, and Pope Innocent VI let her and her daughters enter its cloister seven times a year. She died in 1364, before her son and daughter came to power.
