Irrespective of the historicity of the Iulus of Roman myth, there is little reason to doubt that " Iulus " was an ancient personal name, perhaps even a praenomen, and that " Julius " is a patronymic surname built upon it . " Iullus " seems to be the older spelling, although " Iulus " was more common, and some records mistakenly substitute the more familiar " Tullus " or " Tullius " for it.
