Gaius, On the Edict of the Curule Ædiles, Book I. Or insolent, humpbacked, crooked, or affected with some skin disease, or with the itch, or dumb or deaf:

Gaius, On the Edict of the Curule Ædiles, Book I. A slave who is lame is also considered diseased.

Gaius, On the Edict of the Curule Ædiles, Book I. Where a vendor asserts that a slave has some good quality, and the purchaser complains that this is not true, he will be entitled to an action for the return or the appraisement of the slave, in order to recover the deficiency in his value; for example, if he should say that the slave is steady and industrious, swift of foot, or vigilant, or that he had increased his peculium on account of his frugality; and he, on the contrary, is ascertained to be changeable, insolent, lazy, given to sleep, and a glutton. All these things are considered to signify that what the vendor had asserted cannot be rigorously exacted from him, but that he must be treated with some degree of moderation; so that, for instance, if he declared that the slave was steady, such gravity and constancy as would be shown by a philosopher ought not to be expected from him; and if he asserted that he was industrious and vigilant, constant labor by day and night should not be required of him; but all these qualities he should be expected to possess to a certain extent, according to what is proper and just. We understand the same rule to apply to any other statements which the vendor may make. 1Where the vendor says that the slave is an excellent cook, he must furnish one of the very best belonging to that calling. If, however, he should merely say that he was a cook, he is held to have complied with his statement if he furnishes a cook of moderate ability. The same rule applies to other skilled laborers. 2Again, if anyone should merely assert that the slave has a peculium, it is sufficient if he has only a very small peculium.

Gaius, On the Edict of the Curule Ædiles, Book I. If, however, the statement was made some time before the sale, and then a stipulation was entered into several days afterwards, Cælius Sabinus says that the purchaser can institute proceedings on this ground from the day when the slave was sold.

Gaius, On the Edict of the Curule Ædiles, Book I. And that neither he nor his heir will do anything to prevent the vendor from recovering his slave.

Gaius, On the Edict of the Curule Ædiles, Book I. Generally speaking, it must be held that whatever the slave has acquired from the purchaser otherwise than in managing his property, it seems to be just should be returned.

Gaius, On the Edict of the Curule Ædiles, Book I. Let us see whether it is not unjust for the purchaser to be compelled to surrender the property, and have recourse to the action on judgment, if he could not recover anything on account of the property of the vendor; and should not matters be so arranged that the purchaser can give security to restore the slave if the purchase-money is refunded to him within a certain time?

Gaius, On the Edict of the Curule Ædiles, Book I. Where a vendor does not furnish security with reference to the matters mentioned in the Edict of the Ædiles, they promise an action against him for the return of the property within two months; or one to the extent of the interest of the purchaser, within six months.

Ad Dig. 21,1,45Windscheid: Lehrbuch des Pandektenrechts, 7. Aufl. 1891, Bd. II, § 394, Note 2.Gaius, On the Edict of the Curule Ædiles, Book I. An action for the return of a slave has a twofold effect, for sometimes the vendor will have judgment rendered against him for double damages, and sometimes merely for simple damages. For if he refuses to refund either the price of the slave or any accessories attaching to him, and will not release him from the liability incurred on his account, he will be ordered to pay double the amount of the price and the accessories. Where, however, he returns the price and the accessories or releases the slave from the obligation incurred for his benefit, judgment for simple damages should be rendered against him.
