Concerning the prevalence of the organization into gentes among the Italian tribes, Niebuhr remarks as follows: “Should any one still contend that no conclusion is to be drawn from the character of the Athenian gennē**tes to that of the Roman gentiles, he will be bound to show how an institution which runs through the whole ancient world came to have a completely different character in Italy and in Greece.... Every body of citizens was divided in this manner; the Gephyræans and Salaminians as well as the Athenians, the Tusculans as well as the Romans.”[284]
Besides the existence of the Roman gens, it is desirable to know the nature of the organization; its rights, privileges and obligations, and the relations of the gentes to each other, as members of a social system. After these have been considered, their relations to the curiæ, tribes, and resulting people of which they formed a part, will remain for consideration in the next ensuing chapter.
After collecting the accessible information from various sources upon these subjects it will be found incomplete in many respects, leaving some of the attributes and functions of the gens a matter of inference. The powers of the gentes were withdrawn, and transferred to new political bodies before historical composition among the Romans had fairly commenced. There was, therefore, no practical necessity resting upon the Romans for preserving the special features of a system substantially set aside. Gaius, who wrote his Institutes in the early part of the second century of our era, took occasion to remark that the whole jus gentilicium had fallen into desuetude, and that it was then superfluous to treat the subject.[285] But at the foundation of Rome, and for several centuries thereafter, the gentile organization was in vigorous activity.
The Roman definition of a gens and of a gentilis, and the line in which descent was traced should be presented before the characteristics of the gens are considered. In the Topics of Cicero a gentilis is defined as follows: Those are gentiles who are of the same name among themselves. This is insufficient. Who were born of free parents. Even that is not sufficient. No one of whose ancestors has been a slave. Something still is wanting. Who have never suffered capital diminution. This perhaps may do; for I am not aware that Scaevola, the Pontiff, added anything to this definition.[286] There is one by Festus: “A gentilis is described as one both sprung from the same stock, and who is called by the same name.”[287] Also by Varro: As from an Aemilius men are born Aemilii, and gentiles; so from the name Aemilius terms are derived pertaining to gentilism.[288]
Cicero does not attempt to define a gens, but rather to furnish certain tests by which the right to the gentile connection might be proved, or the loss of it be detected. Neither of these definitions show the composition of a gens; that is, whether all, or a part only, of the descendants of a supposed genarch were entitled to bear the gentile name; and, if a part only, what part. With descent in the male line the gens would include those only who could trace their descent though males exclusively; and if in the female line, then through females only. If limited to neither, then all the descendants would be included. These definitions must have assumed that descent in the male line was a fact known to all. From other sources it appears that those only belonged to the gens who could trace their descent through its male members. Roman genealogies supply this proof. Cicero omitted the material fact that those were gentiles who could trace their descent through males exclusively from an acknowledged ancestor within the gens. It is in part supplied by Festus and Varro. From an Aemilius, the latter remarks, men are born Aemilii, and gentiles; each must be born of a male bearing the gentile name. But Cicero’s definition also shows that a gentilis must bear the gentile name.
In the address of the Roman tribune Canuleius (445 B. C.), on his proposition to repeal an existing law forbidding intermarriage between patricians and plebeians, there is a statement implying descent in the male line. For what else is there in the matter, he remarks, if a patrician man shall wed a plebeian woman, or a plebeian man a patrician woman? What right in the end is thereby changed? The children surely follow the father, (nempe patrem sequuntur liberi.)[289]
A practical illustration, derived from transmitted gentile names, will show conclusively that descent was in the male line. Julia, the sister of Caius Julius Caesar, married Marcus Attius Balbus. Her name shows that she belonged to the Julian gens.[290] Her daughter Attia, according to custom, took the gentile name of her father and belonged to the Attian gens. Attia married Caius Octavius, and became the mother of Caius Octavius, the first Roman emperor. The son, as usual, took the gentile name of his father, and belonged to the Octavian gens.[291] After becoming emperor he added the names Caesar Augustus.
In the Roman gens descent was in the male line from Augustus back to Romulus, and for an unknown period back of the latter. None were gentiles except such as could trace their descent through males exclusively from some acknowledged ancestor within the gens. But it was unnecessary, because impossible, that all should be able to trace their descent from the same common ancestor; and much less from the eponymous ancestor.
