At one point, the very prescient fool speaks of "a green thought in a green shade." The gorgeous phrasing, of course, is from "The Garden" by Andrew Marvell (1621-1678) [pictured]:
Meanwhile the mind, from pleasure less,
Withdraws into its happiness:
The mind, that ocean where each kind
Does straight its own resemblance find;
Yet it creates, transcending these,
Far other worlds, and other seas;
Annihilating all that's made
To a green thought in a green shade.
So Will, speaking in 1537 (the year of Seymour's passing) is anachronizing by over a century.
