Salvete! It's all pretty clear except for the last few sentences. My troubles begin with "et quesita a maiore etc".
Maybe something like "after seeking a sentence by the greater one, the others replied, "He is in your hands." He then ordered that one of them pierce his heart through with a glowing sword per verticem, and that another one hinder him per plantam. Meanwhile, the king comes over and encourages him in his usual way. The knight replies, "My lord, it's too late for me, for a sentence has already been passed upon me and that because I was too blinded by riches, pleasures, and honors, when I was in thy service, hoping that I would always be like this." And having said that, he expired miserably.
As always, any input greatly appreciated.
