 Monasticism provided much needed technological and economic improvements, as the monks which immigrated to inhabit the new foundations and the reformed old ones brought with them collections of books and knowledge of more efficient agricultural and construction techniques, as well as connections to the wider Christian world.There is some discrepancy over the foundation of Santa Maria de Bonarcado, but it seems likely that Constantine laid its foundation around the year 1100.He put it under the authority of the Camaldolese abbey of San Zenone in Pisa instead of the monastery of Saint-Victor in Marseille, which was the great monastic power in the rival giudicato of Cagliari.
