Beware the Ides of March!

By Greg Woolf


Romans measured time in months but not in weeks. The Ides simply meant the middle day of a month and it functioned simply as a temporal navigation aid — one that looks clumsy to us. So one might make an appointment for two days before the Ides or for three days after the Kalends (the first day of the month) and so on. A man shouting from the back of the crowd “Beware the Ides of March!” must have sounded about as sane as a heckler yelling to a modern day politician that he should watch out for the third Tuesday in April.

But for us the Ides of March has only one meaning: the date in 44 BC when Julius Caesar was murdered by a crowd of senators led by his protégés Brutus and Cassius. Tyrannicide, treachery, pathos. And the cry “Beware the Ides of March!” is forever the warning that was ignored.


This we owe to William Shakespeare who made his murder the focal point of the tragedy Julius Caesar. The play is punchy and the action moves fast. It opens in the streets of Rome, where the people are preparing to welcome Caesar home in triumph after the defeat of his civil war rival Pompey. Meanwhile aristocrats mutter over the loss of freedom. Brutus agonizes, torn between his love for Caesar and his hatred of tyranny. The murder itself occurs at almost the exact center of the play. The outcome is briefly uncertain — will the Roman people hail Brutus and Cassius as liberators, or condemn them as murderers? Then Mark Antony, Caesar’s right-hand man, sways the crowd with a passionate funeral oration. The rest of the play follows the flight of the conspirators, their defeat in battle at Philippi, at the hands of Antony and Caesar’s heir Octavius, and their subsequent suicides. Brutus earns the shortest of obituaries from his enemies before Octavius’ closing lines “So call the field to rest, and let’s away, to part the glories of this happy day.”

The Ides themselves were not a happy day, according to Suetonius, one of Caesar’s ancient biographers. The Ides of March had been declared the Day of Parricide, and the senate was forbidden ever to meet again on that date. For things had not turned out as Brutus hoped. By Suetonius’ day it was possible to see Julius Caesar as the first of the Roman emperors, all of whom — beginning from Octavius — took Caesar’s name as a kind of title. An entire mythology had grown up of signs that had marked Caesar’s imminent death and even his subsequent transformation into a god. As Caesar’s wife Calpurnia puts it:

When beggars die there are no comets seen
The heavens themselves blaze forth the death of princes

“Beware the Ides of March!” was just one prophesy among others that transformed Caesar’s murder from a sordid and ultimately pointless crime into an event of cosmic significance. The deaths of emperors (like their births, when viewed in retrospect) were always marked by omens. Emperors were absolute rulers in their lifetime and gods in waiting. How could their deaths be ordinary? And how could their murder even be justified?

Tyrannicide was no more popular under the reigns of Elizabeth I (when the play was first performed) or of her successor James (when it was first printed). Yet political murder and dilemmas like that of Brutus were definitely still on the agenda. Mary Queen of Scots, for example — Elizabeth’s cousin and James’ mother — had been executed for treason just a decade before Julius Caesar was first staged. These issues still mattered.

And Shakespeare’s audience knew this story in advance. A vast mass of the detail of this play, as of Antony and Cleopatra, was drawn from the Lives of the Noble Grecians and Romans, written by Suetonius’ contemporary Plutarch but first translated into English in 1579, a generation before Julius Caesar began to be performed. Plutarch’s Lives, which mined classical history for morally improving tales, were fantastically popular in the early modern period and indeed remained so well into the eighteenth century. Shakespeare’s audience knew from the start that Caesar would die, who would kill him, and even that young Octavius would turn out to be a greater tyrant than Caesar had ever tried to be.

So the soothsayer’s cry “Beware the Ides of March” was not a plot-spoiler. For Shakespeare this warning, and all the others, were devices to raise the tension and focus our attention on the pivotal moment of the murder. As in a thriller today, the excitement is in the obstacles put in the way of the plot. Caesar must die. But what if he listens to his wife’s terrible nightmares? or heeds the soothsayer’s warning? or reads the written warning pushed into his hand by Artemidorus “Delay not Caesar, read it instantly!” (Caesar does not.)

Shakespeare has transformed the signs of cosmic sympathy into mood music. His opening scenes are overshadowed by storms. And again before the death of Brutus there is another omen. Plutarch’s Life of Brutus tells how a monstrous figure had appeared in his tent before the final campaign. Asked its name, it replies “I am your evil demon, Brutus, and I will see you at Philippi!” then vanishes. Shakespeare tells the story almost word for word, but add the stage direction reads Enter the Ghost of Caesar. Brutus’ imminent tragedy points back to the Ides.

Shakespeare’s Renaissance audiences and readers knew the history of Rome as a history of violence. They were drawn more to the chaos of the Republic than to the imperial peace that followed it. And they certainly did not believe in closure. The story of Julius Caesar is not self-contained, and the conflicts are not resolved. It opens with two tribunes remembering how Pompey had once been just as much adored by the Roman people, as his conqueror was now. And Octavius’ last words remind us that Antony and Octavius would immediately fall out over how exactly to “part the glories” (that is to divide the spoils). There would be fresh civil wars, more treachery and many, many more murders to come. Beware the Ides of March!
