LIVES OF THE NOBLE 
 
MARCUS    ‘or griefe with thee, which requireth secrecy and fidelity? 
BRUTUS    ‘I confesse, that a womans wit commonly is too weake to 
    ‘keepe a secret safely: but yet, Brutus, good educacion, 
    ‘and the companie of vertuous men, have some power to 
    ‘reforme the defect of nature. And for my selfe, I have  
    ‘this benefit moreover: that I am the daughter of Cato, 
    ‘and wife of Brutus. This notwithstanding, I did not trust 
    ‘to any of these things before: untill that now I have found 
    ‘by experience, that no paine nor griefe whatsoever can 
    ‘overcome me.’ With those wordes she shewed him her 
    wounde on her thigh, and tolde him what she had done to 
    prove her selfe. Brutus was amazed to heare what she 
    sayd unto him, and lifting up his handes to heaven, he 
    besought the goddes to geve him the grace he might bring 
    his enterprise to so good passe, that he might be founde 
    a husband, worthie of so noble a wife as Porcia: so he then 
    did comfort her the best he coulde. Now a day being 
    appointed for the meeting of the Senate, at what time they 
    hoped Caesar woulde not faile to come: the conspirators 
    determined then to put their enterprise in execucion, bicause 
    they might meete safelie at that time without suspicion, and 
    the rather, for that all the noblest and chiefest men of the 
    citie woulde be there. Who when they should see suche 
    a great matter executed, would everie man then set to their 
    handes, for the defence of their libertie. Furthermore, they 
    thought also that the appointment of the place where the 
    counsell shoulde be kept, was chosen of purpose by divine 
    providence, and made all for them. For it was one of the 
    porches about the Theater, in the which there was a certaine 
    place full of seates for men to sit in, where also was set up 
    the image of Pompey, which the citie had made and con- 
    secrated in honor of him: when he did beawtifie that parte 
    of the citie with the Theater he built, with divers porches 
    about it. In this place was the assembly of the Senate 
    appointed to be, just on the fifteenth day of the moneth of 
    March, which the Romanes call, Idus Martias: so that it 
    seemed some god of purpose had brought Caesar thither to 
    be slaine, for revenge of Pompeys death. So when the day 
    was come, Brutus went out of his house with a dagger by his
