Giraldus claimed that he had heard about Eleanor's adultery with Geoffrey from the saintly Bishop Hugh of Lincoln, who had learned of it from Henry II of England, Geoffrey's son and Eleanor's second husband. Eleanor was estranged from Henry at the time Giraldus was writing, and the king was trying to secure an annulment of their marriage from the Pope. It would have been to his advantage to declare her an adulterous wife who had had carnal relations with his father, for that in itself would have rendered their marriage incestuous and would have provided prima facie grounds for its dissolution.
