Professor MacCallum, commenting upon this account says: “It is interesting to note how Shakespeare takes this passage to pieces, and assigns those of them for which he has a place to their fitting and effective position. Plutarch’s reflections on destiny and Caesar’s opinion on death he leaves aside. The first warning of the soothsayer he refers back to the Lupercalia, and the second he shifts forward to its natural place. Calpurnia’s outcries in her sleep and her prophetic dream, the apparition of the ghosts mentioned by her among the other prodigies, the lack of the heart in the sacrificial beast, are reserved for the scene of her expostulation with Caesar, and are dramatically distributed among the various speakers; Caesar, the servant, Calpurnia herself.”[27]

Pescetti also takes this same passage[28] and distributes the various sections in a manner similar to Shakespeare’s treatment, but dramatically infinitely inferior. He, however, devotes nearly two hundred and fifty lines at the beginning of the third act of “Cesare” to a dialogue between Antony and Caesar, rather tediously moralizing on destiny and Caesar’s opinion on death. The only purpose, dramatically, is to continue the feeling of impending disaster created in the previous acts and to give Antony an opportunity of warning Caesar to beware of treachery.[29] The warnings of the soothsayer are entirely disregarded; the only intimation we receive of this very effective scene is the announcement of the messenger in the fifth act that a paper which gave all the details of the conspiracy, and which Caesar had had no opportunity to read, had been found clutched in his dead hand. Nearly half his second act is occupied by a long drawn out dialogue between Calpurnia and the servant regarding the former’s fears, and the terrible dream she has had. The Priest, in the third act, together with Calpurnia, recounts the portents to Caesar, and tries to dissuade him from disregarding the manifest tokens of the gods’ displeasure. The inspection of the sacrificial beast without a heart is reserved for the expostulation of the Priest. Pescetti, like Shakespeare, thus attempts a distribution of the supernatural which tends to emphasize the impending catastrophe and to invest his play in an atmosphere of portent very similar to that created in “Julius Caesar.”
