Il collegio gesuitico di Santa Croce nel castello di Cagliari: documenti inediti

The research carried out into the Archive of the Roman Society of Jesus (Division Sardinia), allows to fully outline the troubled constructional event of Cagliari’s Jesuit collegiate Complex in the second half of XVI century. This is because the research runs through the main steps again about the Loyolean Order’s earliest times of stay in Cagliari, from the first Jesuit Father's arrival, Pietro Spiga, on May 14th 1557, to the laying of the foundation stone of the Saint Cross Church in November 1594.Trustworthy documents allow to advance by over two years the Society's arrival date in Sardinia, in comparison to the one so far now considered reliable, November 16th 1559. It is furthermore cleared up the time-recording of the rotations in the supervision of works by different Jesuit architects: the ticenese (from Canton of Ticino, Switzerland) brother Gian Domenico de Verdina and the intelvese (from Intelvi Valley, in the province of Como, Italy ) Giovanni Maria Bernardoni, It’s at Giovanni Maria Bernardoni’s school that two islanders were formed: Brother Gavino Crisostomo Cayna, "faber murarius", and the "Praefectus fabricae ecclesiae" Father Luca Ca olacho, being these last ones active above all in the building yard of Saint Cross Church.
