BRUTUS    Consul, whether the Senate would or not, when he was yet 
    but a strippling or springal of twenty yeare old, as him selfe

    Consul, he presently appoynted Iudges to accuse Brutus and 
    his companions, for killing of the noblest person in Rome, 
    and chiefest Magistrate, without law or judgement: and 
    made L. Cornificius accuse Brutus, and M. Agrippa, Cassius. 
Brutus    So, the parties accused were condemned, bicause the Iudges 
accused, and    were compelled to give such sentence. The voyce went, 
condemned,    that when the Herauld (according to the custom after sen- 
by Octavius    tence given) went up to the chair or pulpit for orations, and 
Caesars    proclaymed Brutus with a lowd voyce, summoning him to
