Ptolemy, the son of Lagus, in a letter to Seleucus, just reversed the usual order, bidding him Hail at the beginning, and adding Rejoice at the end instead of wishing him Health; this is recorded by Dionysodorus, the collector of his letters. The case of Pyrrhus the Epirot is well worth mention; as a general he was only second to Alexander, and he experienced a thousand vicissitudes of fortune. In all his prayers, sacrifices, and offerings, he never asked for victory or increase of his royal dignity, for fame or excessive wealth; his whole prayer was always in one word, Health; as long as he had that, he thought all else would come of itself. And it was true wisdom, in my opinion; he remembered that all other good things are worthless, if health is wanting. Oh, certainly (says some one); but we have assigned each form to its proper place by this time; and if you disregard that--even though there was no bad meaning in what you did say--you cannot fairly claim to have made no mistake; it is as though one should put a helmet on the shins, or greaves on the head. My dear sir (I reply), your simile would go on all fours if there were any season at all which did not require health; but in point of fact it is needed in the morning and at noonday and at night --especially by busy rulers like you Romans, to whom physical condition is so important. And again, the man who gives you Joy is only beginning auspiciously; it is no more than a prayer; whereas he who bids you Hail is doing you a practical service in reminding you of the means to health; his is more than a prayer, it is a precept. Why, in that book of instructions which you all receive from the Emperor, is not the first recommendation to take care of your health? Quite rightly; that is the condition precedent of efficiency. Moreover, if I know any Latin, you yourselves, in _returning_ a salutation, constantly use the equivalent of Health. However, all this does not mean that I have deliberately abandoned Rejoice and substituted Hail for it. I admit that it was quite unintentional; I am not so foolish as to innovate like that, and exchange the regular formulae. No, I only thank Heaven that my stumble had such very fortunate results, landing me in a better position than I had designed; may it not be that Health itself, or Asclepius, inspired me to give you this promise of health? How else should it have befallen me? In the course of a long life I have never been guilty of such a confusion before. Or, if I may not have recourse to the supernatural, it is no wonder that my extreme desire to be known to you for good should so confuse me as to work the contrary effect. Possibly, too, one might be robbed of one's presence of mind by the crowd of military persons pushing for precedence, or treating the salutation ceremony in their cavalier fashion.
