I began to write expecting my task to be very difficult, but found plenty of material as I went on. I will defer it, however, till I have cleared the way with a few necessary remarks on the three forms--Rejoice or Joy, Prosper or Prosperity, Hail or Health. Joy is a very ancient greeting; but it was not confined to the morning, or the first meeting. They did use it when they first saw one another: Joy to thee, Lord of this Tirynthian land! But again at the moment when the wine succeeded to the meal: Achilles, Joy! We lack not fair repast-- so says Odysseus discharging his embassy. And even at parting: Joy be with you! And henceforth know me God, No longer mortal man. In fact the apostrophe was not limited to any particular season, as now to the morning alone; indeed they used it on gloomy, nay, on the most lamentable occasions; in Euripides, Polynices ends his life with the words, Joy with you! for the darkness closes on me. Nor was it necessarily significative of friendliness; it could express hatred and the determination to see no more of another. To wish much joy to, was a regular form for ceasing to care about. The modern use of the word dates back to Philippides the dispatch-runner. Bringing the news of Marathon, he found the archons seated, in suspense regarding the issue of the battle. 'Joy, we win!' he said, and died upon his message, breathing his last in the word Joy. The earliest letter beginning with it is that in which Cleon the Athenian demagogue, writing from Sphacteria, sends the good news of his victory and capture of Spartans at that place. However, later than that we find Nicias writing from Sicily and keeping to the older custom of coming to business at once with no such introduction. Now the admirable Plato, no bad authority on such matters, would have us reject the salutation Joy altogether; it is a mean wish, wanting in seriousness, according to him; his substitute is Prosperity, which stands for a satisfactory condition both of body and soul; in a letter to Dionysius, he reproves him for commencing a hymn to Apollo with Joy, which he maintains is unworthy of the Pythian, and not fit even for men of any discretion, not to mention Gods.
