[PAULUS libro quinto epitomarum Alfeni Vari digestorum. ] §13.7.30.prQui ratiario crediderat, cum ad diem pecunia non solueretur, ratem in flumine sua auctoritate detinuit: postea flumen creuit et ratem abstulit.
[PAULUS, Book 5 of the Epitomes of Alfenus Varus' Digest.] A person who had lent money to a boatman, since the money was not paid on the due date, detained the boat in the river on his own authority. Afterwards, the river rose and carried away the boat.
si inuito ratiario retinuisset, eius periculo ratem fuisse respondit: sed si debitor sua uoluntate concessisset, ut retineret, culpam dumtaxat ei praestandam, non uim maiorem.
He answered that if he had retained it against the will of the boatman, the boat was at his own risk; but if the debtor had of his own free will consented to his retaining it, he was liable only for negligence, not for force majeure.
