Abstract: In her quest for sources of the medieval monarchy, Elizabeth Brown encounters Jean Du Tillet, clerk of the Paris parliament. Immersed in the thinking of the American ceremonialists, she revives the question of the lit de justice (bed of justice) that Du Tillet records in the parliamentary registers. She observes his monarchist zeal in the Grand recueil des roys, in his presentation of the ordo of the coronation, and in his polemical and Gallican leanings. She also brings to light important aspects of the sixteenth century.
