The Eyes of March Are Upon You

Caesar:
Who is it in the press that calls on me?
I hear a tongue shriller than all the music
Cry "Caesar!" Speak, Caesar is turn'd to hear.

Soothsayer:
Beware the ides of March.

Caesar:
What man is that?

Brutus:
A soothsayer bids you beware the ides of March.

Julius Caesar Act 1, scene 2, 15–19
-Shakespeare


From my 2005 post, on this Ides of March word play:

For what it is worth, Julius Caesar's cronies conspired and stabbed him to death on this day in 44 B.C.

There is a surgical procedure, an abdominal incision, for the delivery of a baby named after this Roman emperor's legendary birth; the Caesaren-Section.

One way or another, Julius Caesar was on the cutting edge of history.
