In 1610 three of his works came out: "Jani Anglorum Facies Altera" ("The Back Face" "Two Faces" "of the English Janus") and "England's Epinomis", which dealt with the progress of English law down to Henry II; and "The Duello, or Single Combat", in which he traced the history of trial by battle in England from the Norman Conquest. In 1613 he supplied a series of notes, including quotations and references, to the first eighteen cantos of Michael Drayton's "Poly-Olbion". In 1614 he published "Titles of Honor", which, in spite of defects and omissions, remained a comprehensive work for centuries. It was republished in a larger and greatly revised edition in 1631 and earned for Selden the praise "monarch of letters" from his friend Ben Jonson.
