Last year when reading the book of Polybius I was deeply impressed by the story of Popilius, in which he, all alone, stops the ambitious Antiochus IV's whole army at the gate of Egypt by a single and simple gesture. For a detailed account you can refer to the link below:

Therefore I made a vignette depicting this legendary scene. "Before you step out of that circle give me a reply to lay before the senate."
