The Oak and the Brier in The Shepheardes Calender

Philip Sidney created one-way anagram in his Song for an Accession Day Tilt (1577). In the song, Philisides and Mira can be easily transformed to Philip Sidney and Mary.

Next important issue is The Shepheardes Calender (TSC, 1579). All names in TSC are carefully selected based on Sidney's method. One quick example is the tale of the Oak and the Brier.
Which made this foolish Brier wex so bold,
That on a time he cast him to scold,
And sneb the good Oak, for he was old. (TSC, February)
"Foolish Brier" can spell Frier. Frier is an obsolete form of Friar. "Good Oak" can spell God. Oak is an obsolete form of yoke. This can be affirmed by Palinode's lines:
Good is no good, but if it be spend:
God giveth good for none other end. (TSC, May)
So what is that "Husbandman" that cuts the "good Oak"?
It's Human.

"Marley, the Muse's Darling" -- George Peele

George Peele's advice to Christopher Marlowe in Ad Maecenatum Prologus.

Marley, the Muse's darling for thy verse,
Fit to write passions for the souls below,
If any wretched souls in passion speak?
Why go not all into the Elysian fields,
And leave this centre barren of repast, [5]

Unless in hope Augusta will restore
The wrongs that learning bears of covetousness,
And court's disdain, the enemy to art?
Leave, foolish lad, it mendeth not with words;
Nor herbs nor time such remedy affords. [10]

[5] And leave this centre barren of repast,
"barren of repast":: Wilton House cannot afford the "Why go not all."
[6] Unless in hope Augusta will restore
Augustus (63 BC-14 AD) was a patron of literature (Virgil, Horace, Ovid).
"Augusta":: a title to the wife of Roman emperor.
"in hope Augusta":: indicating a powerful patroness in Peele's time.
"Augusta":: Mary Sidney, an august patroness, based on the "Muse's darling."

"foolish lad":: Kit Marlowe.
"mendeth not with words":: Marlowe's hard working in the Elysian fields for the Herberts cannot mend his sin.
[10] Nor herbs nor time such remedy affords.

Thomas Anson's Relief, Shugborough Inscription

The Shepherd’s Monument was commissioned by Thomas Anson (1695-1773), a member of the Dilettanti (Dilettante) Society and Divan Club. Its inscription contains only ten letters in two lines. Above the inscription is a relief of mirrored Et in Arcadia Ego by Nicolas Poussin (1594-1665). It seems that Anson tried to reflect something by that relief.
