William Shakespeare: Julius Caesar, Act II, Scene III
Enter Artemidorus, reading a paper
'Caesar, beware of Brutus; take heed of Cassius; come not near Casca; have an eye to Cinna, trust not Trebonius: mark well Metellus Cimber: Decius Brutus loves thee not: thou hast wronged Caius Ligarius. There is but one mind in all these men, and it is bent against Caesar. If thou beest not immortal, look about you: security gives way to conspiracy. The mighty gods defend thee! Thy lover, 'Artemidorus.' Here will I stand till Caesar pass along, And as a suitor will I give him this. My heart laments that virtue cannot live Out of the teeth of emulation. If thou read this, O Caesar, thou mayst live; If not, the Fates with traitors do contrive.
