When he thought himself strong enough to succeed in anything that he might attempt, he sent one of his friends to his father at Rome to ask what he wished him to do now that the gods had given him sole and absolute power in Gabii. To this messenger no verbal reply was given, because, I believe, he mistrusted him.
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.
