MARCUS    drawen in his hande readie to strike at him: then he let 
BRUTUS    Cascaes hande goe, and casting his gowne over his face, 
    suffered everie man to strike at him that woulde. Then the 
    conspirators thronging one upon an other bicause everie man  
    desirous to have a cut at him, so many swords and 
    daggers lighting upon one bodie, one of them hurte an 
    other, and among them Brutus caught a blowe on his hande, 
    bicause he would make one in murdering of him, and all 
    the rest also were every man of them bloudied. Caesar 
    being slaine in this maner, Brutus standing in the middest 
    of the house, would have spoken, and stayed the other 
    Senators that were not of the conspiracie, to have tolde 
    them the reason why they had done this facte. But they 
    as men both affrayd and amazed, fled one upon anothers 
    necke in haste to get out at the dore, and no man followed 
    them. For it was set downe, and agreed betwene them, 
    that they should kill no man but Caesar onely, and should 
    intreate all the rest to looke to defend their libertie. All 
    the conspirators, but Brutus, determining upon this matter, 
    thought it good also to kill Antonius, bicause he was a 
    wicked man, and that in nature favored tyranny: besides 
    also, for that he was in great estimation with souldiers, 
    having bene conversant of long time amongest them: and 
    specially, having a mind bent to great enterprises, he was 
    also of great authoritie at that time, being Consul with 
Why Anto-    Caesar. But Brutus would not agree to it. First, for that 
nius was not    he sayd it was not honest: secondly, bicause he told them

Caesar.    but that Antonius being a noble minded and coragious man 
    (when he should knowe that Caesar was dead) would willingly 
    helpe his contry to recover her libertie, having them an 
    example unto him, to follow their corage and vertue. So 
    Brutus by this meanes saved Antonius life, who at that 
    present time disguised him selfe, and stale away. But Brutus
