6 In truth, the Lord is propitious to the Roman Empire, since He has chosen such a prince and father of princes, whose virtue and power, established on such a triumphant height of dominion, rests on such humility, that in valour he has surpassed emperors and priests in humility. What can I wish? What can I desire? You have everything, and therefore I will endeavour to gain the sum of my desires. You, O Emperor, are pitiful, and of the greatest clemency.
