[IDEM libro septuagesimo primo ad edictum. ] §19.2.14.prQui ad certum tempus conducit, finito quoque tempore colonus est: intellegitur enim dominus, cum patitur colonum in fundo esse, ex integro locare, et huiusmodi contractus neque uerba neque scripturam utique desiderant, sed nudo consensu conualescunt: et ideo si interim dominus furere coeperit uel decesserit, fieri non posse Marcellus ait, ut locatio redintegretur, et est hoc uerum.
[THE SAME, On the Edict, book 71] He who leases for a certain time is a tenant even after the time has expired; for the owner, when he allows the tenant to remain on the land, is understood to lease it anew, and contracts of this kind do not strictly require either words or writing, but become valid by bare consent. Therefore, if in the meantime the owner should begin to be insane or should die, Marcellus says that it is impossible for the lease to be renewed, and this is correct.
