Plutarch An seni respublica gerenda sit 11

[11] Certainly the office of king, the most perfect and the greatest of all political offices, has the most cares, labours, and occupations. At any rate Seleucus, they used to tell us, constantly repeated that if people in general knew what a task it was merely to read and write so many letters, they would not even pick up a crown that had been thrown away. And Philip, we are told, when he heard, as he was on the point of encamping in a suitable place, that there was no fodder for the beasts of draught, exclaimed: O Heracles, what a life is mine, if I must needs live to suit the convenience even of my asses! There is, then, a time to advise even a king when he has become an old man to lay aside the crown and the purple, to assume a cloak and a crook, and to live in the country, lest it be thought, if he continues to rule when his hair is grey, that he is busying himself with superfluous and unseasonable occupations. But if it is not fitting to say this about an Agesilaüs or a Numa or a Dareius, let us neither remove a Solon from the Council of the Areopagus nor a Cato from the Senate on account of old age, and let us not advise a Pericles to leave the democracy in the lurch. For anyhow it is absurd that a man when he is young should prance (about upon the platform and then, after having poured out upon the public all those insane ambitions and impulses, when the age arrives which brings wisdom through experience, should give up public life and desert it like a woman of whom he has had all the use.

[11] Moreover, the regal dignity, which is the perfectest and greatest of all political governments, has exceeding many cares, labors, and difficulties; insomuch that Seleucus is reported ever and anon to have said: If men knew how laborious are only the writing and reading of so many epistles, they would not so much as stoop to take up a diadem thrown on the ground. And Philip, when, being about to pitch his camp in a fair and commodious place, he was told that there was not there forage for his regiments, cried out: O Hercules, what a life is ours, if we must live for the conveniency of asses! It is then time to persuade a king, when he is now grown into years, to lay aside his diadem and purple, and putting on a coarse coat, with a crook in his hand, to betake himself to a country life, lest he should seem to act superfluously and unseasonably by reigning in his old age. But if the very mentioning such a thing to an Agesilaus, a Numa, or a Darius would be an indignity; let us not, because they are in years, either drive away Solon from the council of the Areopagus, or remove Cato out of the senate; nor yet let us advise Pericles to abandon the democracy. For it is besides altogether unreasonable and absurd, that he who has in his youth leaped into the tribunal should, after he has discharged all his furious ambitions and impetuous passions on the public, when he is come to that maturity of years which by experience brings prudence, desert and abandon the commonwealth, having abused it as if it were a woman.
