The literature of this period primarily consists of legal documents, besides the aforementioned Carta de Logu. The first document containing Sardinian elements is a 1063 donation to the abbey of Montecassino signed by Barisone I of Torres. Other documents are the "Carta Volgare" (1070–1080) in Campidanese, the 1080 Logudorese Privilege, the 1089 Donation of Torchitorio (in the Marseille archives), the 1190–1206 Marsellaise Chart (in Campidanese) and an 1173 communication between the Bishop Bernardo of Civita and Benedetto, who oversaw the Opera del Duomo in Pisa. The Statutes of Sassari (1316) and Castelgenovese (c. 1334) are written in Logudorese.
