Tacitus is an unlikely source for our study of Brutus, Cassius, and Cato, as they stand outside the chronological framework of Tacitus’ writings; nonetheless, they do appear a number of times throughout his works, and Tacitus portrays them with nuance and significance. As Brutus, Cassius, and Cato are rarely the precise focus for Tacitus, they are often referred to obliquely or in dialogue or speeches typically regarding treason and liberty.

Tacitus’ contribution to our understanding of Brutus, Cassius, and Cato comes from both his own use of them as markers of political memory and liberty and his examination of how others used Brutus, Cassius, and Cato to make arguments for political liberty or for the basis of accusations of treason.
