DECIMUS— “tenth”
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]
