Philo Judaeus De Agricultura 93

[93] but if after having been taught the art of managing a chariot, you devote greater pains and study to it, and think yourself at last competent and able to manage horses, mount, and take hold of the reins. For thus, even if they are restive, you will not, by being thrown out of the chariot, receive wounds difficult to be cured, and also afford a subject of ridicule to all the spectators who delight in mischief; nor, on the other hand, will you be overwhelmed by your enemies coming against you or running over you from behind, since by your own speed you will outstrip and leave behind those who are coming after you, and you will be able to afford to disregard those who are coming towards you, because of your skill in getting safely out of the way.
