     things for Dionysius sake and benefit, all the while heDION
     trusted him: and when he beganne to mistrust him, then forAND
     anger he made warre with him. Wherefore all his frendesBRUTUS
     did not beleve, but after he had driven out Dionysius, he
     would stablish the government to him selfe, flattering the
     people with a more curteous and gentle title then the name
     of a tyranne. But for Brutus, his verie enemies them selves
     confessed, that of all those that conspired Caesars death, he
     only had no other ende and intent to attempt his enter-
     prise, but to restore the Empire of Rome againe, to her
     former state and government. And furthermore, it was
     not all one thing to deale with Dionysius, as it was to
     have to doe with Iulius Caesar. For no man that knew
     Dionysius, but would have despised him, considering that he
     spent the most parte of his time in drinking, dycing, and in
     haunting lewde womens company. But to have undertaken
     to destroy Iuilius Caesar, and not to have shroncke backe for
     feare of his great wisedom, power, and fortune, considering
     that his name only was dreadfull unto everie man, and also
     not to suffer the kings of Parthia and India to be in rest
     for him: this could not come but of a marvelous noble
     minde of him, that for feare never fainted, nor let fall any
     part of his corage. And therfore, so sone as Dion came
     into Sicilia, many thowsands of men came and joyned with
     him, against Dionysius. But the fame of Iulius Caesar did
     set up his frends againe after his death, and was of suche
     force, that it raised a young stripling, Octavius Caesar, (that
     had no meanes nor power of him selfe) to be one of the
     greatest men of Rome: and they used him as a remedie
     to encounter Antonius malice and power. And if men will
     say, that Dion drave out the tyran Dionysius with force of
     armes, and sundrie battells: and that in contrarie maner
     Brutus slue Caesar, being a naked man, and without gard:
     then doe I aunswere againe, that it was a noble parte, and
     of a wise Captaine, to choose so apt a time and place, to
     come uppon a man of so great power, and to finde him
     naked without his gard. For he went not sodainlie in a
     rage, and alone, or with a small companie, to assaile him:
     but his enterprise was long time before determined of, and
