Presented by Sir John Harrington to King James in 1604 as an attempt to win the new sovereign's favor and patronage, this invaluable manuscript, long thought to be lost, is here published for the first time. It consists of 162 neatly hand-written pages, including an epistle to the king, and Cauchi includes parallel English and Latin texts, marginal explanatory notes, a full introduction and commentary that set the work in the context of Harington's life and literary career, and a complete index.
