     small heate: therefore the ayer being very clowdy and darke,     IULIUS
     by the weakenes of the heate that could not come foorth,CÆSAR
     did cause the earth to bring foorth but raw and unrypeelement after
     frute, which rotted before it could rype. But above all, theCaesars death.
     ghost that appeared unto Brutus shewed plainly, that the 
     goddes were offended with the murther of Caesar. TheA great
     vision was thus: Brutus being ready to passe over his armyComet.
     from the citie of Abydos, to the other coast lying directly 
     against it, slept every night (as his manner was) in his tent,Brutus vision.
     and being yet awake, thinking of his afaires: (for by reporte 
     he was as carefull a Captaine, and lived with as litle sleepe, 
     as ever man did) he thought he heard a noyse at his tent 
     dore, and looking towards the light of the lampe that 
     waxed very dimme, he saw a horrible vision of a man, ofA spirit
     a wonderfull greatnes, and dreadfull looke, which at theappeared
     first made him marvelously afraid. But when he saweunto Brutus.
     that it did him no hurt, but stoode by his bedde side, and 
     sayd nothing: at length he asked him what he was. The 
     image aunswered him: I am thy ill angell, Brutus, and thou 
     shalt see me by the citie of Philippes. Then Brutus replied 
     againe, and sayd: Well, I shall see thee then. Therewithall, 
     the spirit presently vanished from him. After that time 
     Brutus being in battell neere unto the citie of Philippes, 
     against Antonius and Octavius Caesar, at the first battell he 
     wan the victorie, and overthrowing all them that withstoode 
     him, he drave them into young Caesars campe, which he 
     tooke. The second battell being at hand, this spirit ap-The second
     peared again unto him, but spake never a word. Thereupponappearing of
     Brutus knowing he should dye, did put him selfe to allthe spirit,
     hazard in battell, but yet fighting could not be slaine. Sounto Brutus.
     seeing his men put to flight and overthrowen, he ranne unto 
     a litle rocke not farre of, and there setting his swordes 
     point to his brest, fell upon it, and slue him selfe, 
     but yet as it is reported, with the helpe of 
     his frend, that dispatched him.
