This is a well known story concerning Lopez: King Philip II and his chaplain Ruy Lopez were in a hall of the palace of the Escorial. The courtiers were silent at one end of the room.
The door opened and the executioner came in. 'How well', asked the monarch, 'is all set to proceed?' 'Lord, the inmate refuses.' 'How is that?' 'Because if you want to cut off a noble's head he asks to be blessed by a Bishop.'
'Granted, let it be as he wishes, but everything must be done by three o'clock.' The King turned to Ruy Lopez and said 'Arise, Bishop of Zamora, and go to assist the inmate.'
Ruy Lopez, with all the pain of his heart, rose and went to jail, compelled to issue last rites to none other than his close friend, the Duke of Medina Sidonia. The Duke was a former favorite of Philip II, now accused of conspiracy against the King.
