Decimus was a prænomen in the family of Junius Brutus, inherited mayhap from a tenth son, and it was at Decimus Brutus that Cæsar’s dying reproach, Et tu Brute, is thought to have been levelled. Decimus and Decima are now and then to be found among us in unusually large families of one sex. Decius was the name of a great plebeian gens, one of the oldest in Rome, and illustrated by the self-devotion of Decius Mus.[[55]]

CHAPTER III.
NOMINA.
Section I.—Attius.
The Latin nomina were those that came by inheritance, and denoted the position of the gens in the state, its antiquity, and sometimes its origin. Their derivation is often, however, more difficult to trace than that of any other names, being lost in the darkness of the Oscan and Latin dialects; and in the latter times they were very wide-spread, being adopted by wholesale by persons who received the franchise, as Roman citizens, from the individual who conferred it; and after the time of Caracalla, A.D. 212, when all the free inhabitants of the empire became alike Roman citizens, any person might adopt whatever name he chose, or even change his own if he disliked it. The feminine of this gentile name, as it was called, was the inheritance of the daughters; and on marriage, the feminine of the husband’s nomen was sometimes, though not uniformly, assumed.
These names are here placed in alphabetical order, as there seems to be nothing else to determine their position, and it is in accordance with the rigid Roman fashion of regularity.
Thus we begin with the Accian, Attian, or Actian gens; one of no great rank, but interesting as having been fixed on by tradition as the ancestry of the great mountain lords of Este, who were the parents of the house of Ferarra in Italy, and of the house of Brunswick, which has given six sovereigns to Britain. Accius is probably derived from Acca, the mother of the Lares, an old Italian goddess, afterwards turned into the nurse of Romulus. Valerius, however, deduces both it and Appius from a forgotten Sabine prænomen Attus. The Appian gens was not a creditable one; but Appia was sometimes the name of mediæval Roman dames.
The genealogists of the house of Este say that Marcus Actius married Julia, sister of the great Cæsar, and trace their line downwards till modernized pronunciation had made the sound Azzo.
Him whom they count as Azo I. of Este was born in 450, and from him and his descendants Azzo and Azzolino were long common in Italy, though now discarded.
