* Translation of the part about the Ark of the Covenant, in Descriptio Lateranensis Ecclesiae (Reg. lat. 712): “(XX) In the Lateran church, which is the capital of the world, which is a patriarchal or imperial see, there is the pontifical throne of the Apostolic [church], and the principal [altar] of that same church is the Ark of the Lord’s Covenant; or rather, as they say, the Ark is on the inside, and on the outside it is hidden by an altar, which measures the same as the ark in length and width, between four columns of red porphyry, beneath a certain beautiful canopy, in which indeed, as they say, is a great sanctuary; but they do not understand of what kind it is, since they do not know its name.”
