For Dorothy and Thomas, wish you were here

We look at the world once, in childhood. The rest is memory.

NOSTOS BY LOUISE GLUCK

Thank you to Peter Steinberg and Coates Bateman. I am also happily indebted to Nan Talese, Luke Epplin, and everyone at Doubleday, to Joe Regal and the redoubtable Bess Reed. To Melanie for her insightful reading and suggestions and for years of encouragement. To all my children.

For their advice and inspiration, Sam Hazo, David Low, Cliff Becker, Amy Stolls, Ellen Bryson, Gigi Bradford, Allison Bawden, Laura Becker, and Sharon Kangas. And for the swift kick at Whale Rock, thank you to Jane Alexander and Ed Sherin.

Sarah Blaffer Hrdy's Mother Nature: A History of Mothers, Infants, and Natural Selection inspired the journal article on the anthropological roots of the changeling myth.
