He who does not understand the game, abstains from the weapons of the Campus Martius: and the unskillful in the tennis-ball, the quoit, and the troques keeps himself quiet; lest the crowded ring should raise a laugh at his expense: notwithstanding this, he who knows nothing of verses presumes to compose. Why not! He is free-born, and of a good family; above all, he is registered at an equestrian sum of moneys, and clear from every vice. You, [I am persuaded,] will neither say nor do any thing in opposition to Minerva: Invita … Minerva Hor. Ars 385 . Cicero, de Off. i. 31, explains this phrase: "adversante et repugnante natura." And yet the meaning here is not very evident. Does Horace say that young Piso will neither do nor say any thing contrary to his natural endowments; implying that he will not attempt poetry, as his abilities are inadequate? Or does he mean to compliment him on his capabilities, by saying that there is nothing which he will attempt, in which genius will not favor and assist him? The latter appears to be the correct interpretation. Thus the obvious meaning of invita Minerva is — Minerva refusing her assistance, or discountenancing the attempt; and the interpretation-natural endowments refusing their assistance, or marring the effort. such is your judgment, such your disposition. But if ever you shall write any thing, let it be submitted to the ears of Metius [Tarpa], who is a judge, and your father's, and mine; and let it be suppressed till the ninth year, your papers being laid up within your own custody. You will have it in your power to blot out what you have not made public: a word once sent abroad can never return.
