[T]he greatest Man in the whole Commonwealth of Letters (meaning my Lord Somers).

John Somers, 1st Baron Somers (4 March 1651 – 26 April 1716) was an English Whig jurist and statesman. Somers first came to national attention in the trial of the Seven Bishops where he was on their defence counsel. He published tracts on political topics such as the succession to the crown, where he elaborated his Whig principles in support of the Exclusionists. He played a leading part in shaping the Revolution settlement. He was Lord High Chancellor of England under King William III and was a chief architect of the union between England and Scotland achieved in 1707 and the Protestant succession achieved in 1714. He was a leading Whig during the twenty-five years after 1688; with four colleagues he formed the Whig Junto.
