Barisone II Torchitorio IV de Serra[1] (c. 1190 – after 20 April 1217) was the Judike (Judge) of Arborea and Cagliari.
He married Benedetta, the heiress of William I of Cagliari, and succeeded him on that throne.
[2] Torchitorio and Benedetta were related within the prohibited degree, but Pope Innocent III gave them dispensation to marry.
They subsequently did homage to the pope on 18 November 1215, probably to avoid domination by the Republic and Archdiocese of Pisa.
[3] Torchitorio died in 1217 and left a months-old son, William II, who succeeded him in Cagliari, while Hugh's son Peter II maintained himself in all Arborea.
