Final answer:
In Shakespeare's 'Julius Caesar', a soothsayer, not a rhetoric teacher, warns Caesar about the 'Ides of March', foreshadowing his death.
Step-by-step explanation:
The teacher of rhetoric who tries to warn Caesar of his imminent death is a character in William Shakespeare's play, 'Julius Caesar'. In the historical context, this is related to the events leading up to Caesar's assassination in 44 BCE.
However, it is important to note that in Shakespeare's play, a soothsayer, rather than a teacher of rhetoric, warns Caesar to 'beware the Ides of March'.
It is this soothsayer's warning that has become famously associated with the foreshadowing of Caesar's death. The play itself is a dramatic interpretation of the historical events.
Valerius Licinianus, a former senator and eloquent orator, had fallen from grace and became an exile and a mere teacher of rhetoric. When he warned Caesar of his fate, he expressed his bitterness towards fortune.
