On the tide of my vagrant prose

The end of the first chapter, “tuning my piano,” of John Barth’s The Floating Opera:

Why The Floating Opera? I could explain until Judgment Day, and still not explain completely. I think that to understand any one thing entirely, no matter how minute, requires the understanding of every other thing in the world. That’s why I throw up my hands sometimes at the  simplest things; it’s also why I don’t mind spending a lifetime getting ready to begin my Inquiry. Well, The Floating Opera. That’s part of the name of a showboat that used to travel around the Virginia and Maryland tidewater areas: Adam’s Original & Unparalleled Floating Opera; Jacob R. Adam, owner and captain; admissions 20, 35, and 50 cents. The Floating Opera was tied up at Long Wharf on the day I changed my mind, in 1937, and some of this book happens aboard it. That’s reason enough for me to use it as a title. But there’s a better reason. It always seemed a fine idea to me to build a showboat with just one big flat open deck on it, and to keep a play going continuously. The boat wouldn’t be moored, but would drift up and down the river on the tide, and the audience would sit along both banks. They could catch whatever part of the plot happened to unfold as the boat floated past, and then they’d have to wait until the tide ran back again to catch another snatch of it, if they still happened to be sitting there. To fill in the gaps they’d have to use their imaginations, or ask more attentive neighbors, or hear the word passed along from upriver or downriver. Most times they wouldn’t understand what was going on at all, or they’d think they knew, when actually they didn’t. Lots of times they’d be able to see the actors, but not hear them. I needn’t explain that that’s how much of life works: our friends float past; we become involved with them; they float on, and we must rely on hearsay or lose track of them completely; they float back again, and we either renew our friendship—catch up to date—or find that they and we don’t comprehend each other any more. And that’s how this book will work, I’m sure. It’s a floating opera, friend, fraught with curiosities, melodrama, spectacle, instruction, and entertainment, but it floats willy-nilly on the tide of my vagrant prose: you’ll catch sight of it, lose it, spy it again; and it may require the best efforts of your attention and imagination—together with some patience, if you’re an average fellow—to keep track of the plot as it sails in and out of view.
