The fraternal relationship first took shape at home, where inheritance laws and practices fostered cooperation among brothers in managing family property and caring for relatives. Appeals to fraternal pietas in political rhetoric drew a large audience in the forum, because brothers' devotion symbolized the mos maiorum, the traditional morality that grounded Roman politics and celebrated brothers fighting together on the battlefield. Fraternal pietas and fratricide became powerful metaphors for Romans as they grappled with the experience of recurrent civil war in the late Republic and with the changes brought by empire. Mythological figures like Romulus and Remus epitomized the fraternal symbolism that pervaded Roman society and culture. In The Brothers of Romulus, Bannon combines literary criticism with historical legal analysis for a better understanding of Roman conceptions of brotherhood.
