The king went into the palace-garden, deep in thought, his son's messenger following him. As he walked along in silence it is said that he struck off the tallest poppy-heads with his stick.
Tired of asking and waiting for an answer, and feeling his mission to be a failure, the messenger returned to Gabii, and reported what he had said and seen, adding that the king, whether through temper or personal aversion or the arrogance which was natural to him, had not uttered a single word.
When it had become clear to Sextus what his father meant him to understand by his mysterious silent action, he proceeded to get rid of the foremost men of the State by traducing some of them to the people, whilst others fell victims to their own unpopularity. Many were publicly executed, some against whom no plausible charges could be brought were secretly assassinated.
