Remove not the ancient landmark, which thy fathers have set

Googling, as folk are wont to do, the humble phrase "For out of olde feldes, as men seyth" I stumbled across Faithful Magistrates and Republican Lawyers: Creators of Virginia's Legal Culture, 1680-1810² and my heart beat faster - yes really it did - for I had found the elusive connection between the Common Law of Olde Englande and Chaucer, and it is Coke. From Institutes of the Lawes of England (Widely recognized as a foundational document of the common law, they have been cited in over 70 cases decided by the Supreme Court of the United States), probably volume four, we find: Let us now peruse our ancient authors, for out of the old fields must come the new corne. Which runs on, via some obscure connections I've now lost track of¹, to the Rule in Shelley's Case, which you don't want to know about. Even better, from the title page I find Proverbs 22 28: Remove not the ancient landmark, which thy fathers have set.

Notes

1. One is a file on the history of the law of due process, which only belatedly do I notice is from electjudgeduggan.wordpress.com, who (Ballotopedia tells me) was a candidate for Supreme Court 3rd Judicial District in 2013. But he got stoated, receiving only 5% of the vote, despite his fine scholarship.

2. Or perhaps more usefully, William Fitzhugh.
