" This is how Raimbaut saw him, as with quick assured movements he arranged the pine cones in a triangle, then in squares on the sides of the triangle, and obstinately compared the pine cones on the shorter sides of the triangle with those of the square of the hypotenuse. Raimbaut realised that all this moved by ritual, convention, formulas, and beneath it there was ... what? He felt a vague sense of discomfort come over him at knowing himself to be outside all these rules of a game. But then his wanting to avenge his father's death, his ardor to fight, to enroll himself among Charlemagne's warriors—wasn't that also a ritual to prevent plunging into the void, like this raising and setting of pine cones by Sir Agilulf? Oppressed by the turmoil of such unexpected questions, young Raimbaut flung himself to the ground and burst into tears. "
