[POMPONIUS libro uicensimo sexto ad Quintum Mucium. ] §8.2.7.prQuod autem aedificio meo me posse consequi, ut libertatem usucaperem, dicitur, idem me non consecuturum, si arborem eodem loco sitam habuissem, Mucius ait, et recte, quia non ita in suo statu et loco maneret arbor quemadmodum paries, propter motum naturalem arboris.
[POMPONIUS in the twenty-sixth book on Quintus Mucius.] However, as to the statement that I can achieve, by means of my building, the acquisition of freedom by usucapion, Mucius says that I would not achieve the same if I had kept a tree situated in the same place; and this is correct, because a tree, owing to its natural motion, would not remain in its state and place in the same manner as a wall.
