(Paul, Opinions 2.26.1-8, 10-12, 14-17. L)

2.26 (1) In the second chapter of the lex Iulia concerning adultery, either an adoptive or a natural father is permitted to kill with his own hands an adulterer caught in the act with his daughter in his own house or in that of his son-in-law, no matter what his rank may be.

(2) If a son under paternal power, who is the father, should surprise his daughter in the act of adultery, while it is inferred from the words of the law that he cannot kill her, still, he ought to be permitted to do so.

(3) Again, it is provided in the fifth chapter of the lex Julia that it is permitted to detain an adulterer who has been caught in the act for twenty hours, calling neighbours to witness.

(4) A husband cannot kill anyone taken in adultery except persons who are infamous, and those who sell their bodies for gain, as well as slaves. His wife, however, is excepted, and he is forbidden to kill her.

(5) It has been decided that a husband who kills his wife when caught with an adulterer should be punished more leniently, for the reason that he committed the act through impatience caused by just suffering.

(6) After having killed the adulterer, the husband should at once dismiss his wife, and publicly declare within the next three days with what adulterer, and in what place he found his wife.

(7) A husband who surprises his wife in adultery can only kill the adulterer when he catches him in his own house.

(8) It has been decided that a husband who does not at once dismiss his wife whom he has taken in adultery can be prosecuted as a pimp.

(10) It should be noted that two adulterers can be accused at the same time with the wife, but more than that number cannot be.

(11) It has been decided that adultery cannot be committed with women who have charge of any business or shop. [20]

(12) Anyone who has sexual relations with a free male without his consent shall be punished with death.

(14) It has been held that women convicted of adultery shall be punished with the loss of half of their dowry and the third of their goods, and by relegation to an island. The adulterer, however, shall be deprived of half his property, and shall also be punished by relegation to an island; provided the parties are exiled to different islands.

(15) It has been decided that the penalty for incest, which in case of a man is deportation to an island, shall not be inflicted upon the woman; that is to say when she has not been convicted under the lex Julia concerning adultery.

(16) Sexual intercourse with female slaves, unless they are deteriorated in value or an attempt is made against their mistress through them, is not considered an injury.

(17) In a case of adultery a postponement cannot be granted.

lex Julia

20. Not because is is prohibited but in the sense that sexual relations with such women are not considered adultery.
