JULIUS CAESAR By William Shakespeare

Supernatural events take place in Julius Caesar. In Act I, Scene III of the play, Casca has been witness to several omens, relaying them to Cicero in a manner most frightened. “But never till tonight, never till now, Did I go through a tempest dropping fire. - A common slave...Held up his left hand, which did flame and burn Like twenty torches joined; and yet his hand, Not sensible of fire, remained unscorched. - Against the Capitol I met a lion, Who glazed upon me and went surly by Without annoying me. - ...they saw Men all in fire walk up and down the streets. And yesterday the bird of night did sit Even at noonday upon the marketplace,” In Act IV, Scene III, the Ghost of Caesar appears to Brutus, stating they will meet again at Philippi.

One criticism of some literature is that it relies too heavily on the use of the supernatural to advance the plot or provide foreshadowing. Julius Caesar is validly criticized in this way.
Neither of the examples I have provided can really be considered necessary for the preservation of the story; that is, without these excerpts, the story would be relatively the same, without much being lost.

However, Act I’s supernatural sequence is nothing but foreshadowing, as is the second example. Hardly any other methods are taken to foreshadow events. In Scene II of the first Act, a Soothsayer warns Caesar to beware the Ides of March, a soothsayer being one who can see the future.

Even Calphurnia’s account of her dreams to Caesar, horrible events taking place suggest something is wrong (Act II, Scene II), is considered to be supernatural, as it includes a lioness roaming the streets of Rome, zombies and warriors fighting with fire (as their weapons) in the sky.

The supernatural is not the only way Shakespeare conveys foreshadowing though. Act III, Scene I: Brutus shakes the hands of the conspirators, drenching his hand in his fallen comrade's (Caesar's) blood (who fell to the conspirators) beforehand, marking them all for death and later, after the conspirators left, he vows to avenge him.

Although the majority of the story is told without the supernatural being involved, enough of it is present to allow the statement, "Julius Caesar relies too heavily on the supernatural to (advance the plot or) provide foreshadowing," to be a valid conclusion. Not necessarily bashing the book, just an observation; imagination must be used to get some of the details out of the story (which is what makes a story worth reading, details).
