Pope Innocent III writes to the bishops of Orkney and Ross, noting that the nobleman, H[arald], earl of Caithness and Orkney, made known to him that, for the redemption of his sins, from the time of Pope Alexander, his predecessor, the earl set up that 1d. from every house in the earldom of Caithness would be directed to the Apostolic See, which had been collected by A[ndrew], bishop of Caithness. After the bishop’s death, J[ohn], who was instituted as bishop, had prohibited this. The pope thus commands the bishops to compel the said bishop of Caithness to desist from preventing the payment.
