In Speak like a leader, Simon Lancaster says that lessons learned in Roman times about effective political speeches still apply, and it is scandalous that a training in rhetoric is such a rarity. He briefly touches six major lessons in effective speaking, but he does not flesh it out beyond what is permitted in a TED talk.
Briefly, the six lessons or tools are:
The breathless x 3, three short adjectives, nouns, or phrases: "Lies. Treachery. Embezzlement." as the opening to a political smear ad.
The repetition x 3, three sentences repeating the same thing.
The balance x 3, three balanced sentences which are taken to represent balanced thought.
Metaphor, his point being that we all use metaphor and which political metaphor we use can have profound impact on reception.
Exaggeration, by far the most potent tool in any communication. (Err...)
Rhyme: if you've taken the time to make a rhyme, what you're saying must be true, even if you're blue.
What are the ancient classic textssources, offeringancient or modern, providing a foundational treatment of the rhetoric that furnishes his, in which these six highlights were originally proposed?
