“Rock-a-bye baby, in the treetop…”

 In the early 1600s, as Europe was abuzz with Miguel de Cervantes' new novel,
Don Quixote de La Mancha, a woman landed in America to begin a nation and a life. She observed how the Native American women allowed the wind to rock their babies to sleep in birch-bark cradles suspended from the branches of trees.

And a lullabye was born.

The woman's name is lost to history.
