"I've found when you get old you must return to certain things in the beginning, or things you have a sentiment for or something. Because your life closes up in so many ways or doesn't become as flexible or exciting or whatever you want to call it. You tend to be nostalgic. And I think about my boats. It's more complicated than that, but also it's going out and also there's a lot of references to crossing over. But the thing of the Nile boat in Winter's Passage: Luxor was about the wonderful thing, the lazy thing, of being two or three months in Luxor by the river. It was just that, it explains a winter passage. From a certain point to the other side: it's like the Greek boat that ferries you over to the other world. That sculpture didn't have it. But sometimes the large painting in Houston does have it. It's a passage through everything."
