Beware the Ides of March

The Ides of March is the first day of the Roman New Year. It also marks the first day of spring. On this day in history, Julius Caesar was warned by soothsayers to "beware of the Ides of March". Apparently, he did not heed the warning strongly enough as he was stabbed by Marcus Brutus on the Ides of March in 44 BC. Pre Cesar's assassination, the ides of March didn't signify anything special in itself, it was just the usual way of saying March 15th. Each month has an ides. Clearly William Shakespeare was a marketing genius. Everyone knows to beware the ides of March. It's right up there with a diamond is forever.

Julius Caesar
by William Shakespeare
Act 3, Scene 2
Mark Antony:

Friends, Romans, countrymen, lend me your ears;
I come to bury Caesar, not to praise him;
The evil that men do lives after them,
The good is oft interred with their bones,
So let it be with Caesar ... The noble Brutus
Hath told you Caesar was ambitious:
If it were so, it was a grievous fault,
And grievously hath Caesar answered it ...
Here, under leave of Brutus and the rest,
(For Brutus is an honourable man;
So are they all; all honourable men)
Come I to speak in Caesar's funeral ...
He was my friend, faithful and just to me:
But Brutus says he was ambitious;
And Brutus is an honourable man….
He hath brought many captives home to Rome,
Whose ransoms did the general coffers fill:
Did this in Caesar seem ambitious?
When that the poor have cried, Caesar hath wept:
Ambition should be made of sterner stuff:
Yet Brutus says he was ambitious;
And Brutus is an honourable man.
You all did see that on the Lupercal
I thrice presented him a kingly crown,
Which he did thrice refuse: was this ambition?
Yet Brutus says he was ambitious;
And, sure, he is an honourable man.
I speak not to disprove what Brutus spoke,
But here I am to speak what I do know.
You all did love him once, not without cause:
What cause withholds you then to mourn for him?
O judgement! thou art fled to brutish beasts,
And men have lost their reason…. Bear with me;
My heart is in the coffin there with Caesar,
And I must pause till it come back to me.
