Seneca · On the value of retirement
Letters 36.7
If your friend had been born in Parthia, he would have begun, when a child, to bend the bow; if in Germany, he would forthwith have been brandishing his slender spear; if he had been born in the days of our forefathers, he would have learned to ride a horse and smite his enemy hand to hand. These are the occupations which the system of each race recommends to the individual,—yes, prescribes for him.
Seneca, Letters to Lucilius 36.7, translated by Richard Mott Gummere
