Then close thine eyes and rest secure;
No sleep so sweet as thine, no rest so sure.
Francis Quarles(1592 - 1644)
This popular lullaby originally published in 1632 in a collection called Divine Fancies and aplty illustrates that a poet writes best what he knows best: Quarles and his wife had eighteen children.
