L'auteur du texte, Gossuin de Metz, explique que "des pierres jetées au centre de la terre ne sauraient aller plus loin, parce qu’elles seraient alors à égale distance du firmament". Il ajoute que "si ces pierres étaient de poids différents, la plus lourde arriverait au centre avant les autres". Cette enluminure du "Maître de Thomas de Maubeuge" explicite assez fidèlement le propos de l'auteur du texte. Nous savons à présent qu'une pierre abandonnée à la gravité terrestre dans une cavité de dimensions suffisantes creusée dans la Terre décrirait une courbe beaucoup plus complexe que la simple verticale (compte tenu de l'accélération de Coriolis).
