Read this excerpt from The Iliad.

First give thy faith, and plight a prince's word
Of sure protection, by thy power and sword;
For I must speak what wisdom would conceal,
And truths, invidious to the great, reveal,
Bold is the task, when subject, grown too wise
Instruct a monarch where his error lies;

What evidence suggests why Agamemnon may become angry with Chalcas?

First give they faith, and plight a prince's word
Of sure protection, by thy power and sword;

Bold is the task, when subject, grown too wise
Instruct a monarch where his error lies;

And truths, invidious to the great, reveal
Bold is the task, when subject, grown too wise

For I must speak what wisdom would conceal,
And truths, invidious to the great, reveal
