Lucian of Samosata Pro lapsu inter salutandum 2

[2] When I began to write, I thought that I was taking on an impossible task, but as I went on I found plenty to say. But before I tell you this, let me say a few suitable words about these greetings “Joy to you,” “Do well,” and “Health to you.” “Joy to you” is the ancient greeting, not however confined to the morning or to the first meeting, but they used it whenever they first caught sight of one another, as in and after dinner when they were ready to talk over their wine, as in when Odysseus was declaring to him his embassy’s mission. They used it also when they took their leave, as in This greeting was not reserved for a special time, as now only for morning. Indeed even on the most unwelcome and inauspicious occasions they used it nevertheless, as in Euripides when Polynices at the end of his life says It was not just a sign for them of friendly feeling, but also of dislike and final parting. For example, to bid “Joy to it and a long one” meant that they washed their hands of it.
