Q. What is the origin of the quotation displayed in Harvard Law School’s Caspersen Room, “Out of old fields must spring and grow the new corn”?

The motto was a favorite saying of Edward Coke, Chief Justice of England, who borrowed it from Geoffrey Chaucer's The Parliament of Fowles:

For out of olde feldes, as men seith,

Cometh al this newe corn fro yeer to yere;

And out of olde bokes, in good feith,

Cometh al this newe science that men lere.
