Let us notice, in the first place, how little is said in the literature of the time, including biographies, of that period of life which is now so full of interest to readers of memoirs, so full of interest to ourselves as we look back to it in advancing years. It may be that we now exaggerate the importance of childhood, but it is equally certain that the Romans undervalued the importance of it. It may be that we over-estimate the value of our public-school life, but it is certain that the Romans had no such school life to be proud of. Biography was at this time a favourite form of literature, and some of the memoirs then written were available for use by later writers, such as Valerius Maximus, Suetonius, and Plutarch; yet it is curious how little has come down to us of the childhood or boyhood of the great men of the time. Plutarch indeed was deeply interested in education, including that of childhood, and we can hardly doubt that he would have used in his Roman Lives any information that came in his way. He does tell us something, for which we are eternally indebted to him, of old Cato's method of educating his son,[249] and something too, in his _Life of Aemilius Paullus_,[250] of the education of the eldest son of that family, the great Scipio Aemilianus. But in each of these Lives we shall find that this information is used rather to bring out the character of the father than to illustrate the upbringing of the son; and as a rule the Lives begin with the parentage of the hero, and then pass on at once to his early manhood. The Life of the younger Cato, however, is an exception to the rule, which we must ascribe to the attraction which all historians and philosophers felt to this singular character. Plutarch knew the naiue and character of Cato's paedagogus, Sarpedon,[251] and tells us that he was an obedient child, but would ask for the reason of everything, in those questions beginning with "why" which are often embarrassing to the teacher. Two stories in the second and third chapters of this Life are also found in that insipid medley of fact and fable drawn up in the reign of Tiberius, by Valerius Maximus, for educational purposes;[252] a third, which is peculiarly significant, and seems to bear the stamp of truth, is only to be found in Plutarch. I give it here in full: "On another occasion, when a kinsman on his birthday invited some boys to supper and Cato with them, in order to pass the time they played in a part of the house by themselves, younger and older together: and the game consisted of accusations and trials, and the arresting of those who were convicted. Now one of the boys convicted, who was of a handsome presence, being dragged off by an older boy to a chamber and shut up, called on Cato for aid. Cato seeing what was going on came to the door, and pushing through those who were posted in front of it to prevent him, took the boy out; and went off home with him in a passion, accompanied by other boys."
