Heracles, the Greek hero, is a guest at Admetus’ house in Thessaly.
HERACLES Hey, you! Why so solemn and anxious? A servant should not be sullen with guests, but greet them with a cheerful heart.
You see before you a man who is your lord's friend, and you greet him with a gloomy, frowning face, because of your zeal about a strange woman's death. Come here, and let me make you a little wiser! (With drunken gravity) Know the nature of human life? Don't think you do. You couldn't. Listen to me. All mortals must die. Isn't one who knows if he'll be alive to-morrow morning. Who knows where Fortune will lead? Nobody can teach it. Nobody learn it by rules. So, rejoice in what you hear, and learn from me! Count each day as it comes as Life-and leave the rest to Fortune. Above all, honour the Love Goddess, sweetest of all the Gods to mortal men, a kindly goddess! Put all the rest aside. Trust in what I say, if you think I speak truth-as I believe. Get rid of this gloom, rise superior to Fortune. Crown yourself with flowers and drink with me, won't you? I know the regular clink of the wine-cup will row you from darkness and gloom to another haven. Mortals should think mortal thoughts. To all solemn and frowning men, life I say is not life, but a disaster.
