Second but only surviving son of John, Lord Harington of Exton and Burley, Rutland.
As a courtier and heir to large estates, his youth is more fully documented than most.
Harington was one of the aristocratic companions of Prince Henry, who was two years his junior. The closeness of the relationship is illustrated by a joint portrait in which Harington holds a stag down as Henry prepares for the kill.
Harington, like the prince, was regarded as an exemplary scholar.
Harington’s tour of the Continent, begun in the summer of 1608. Before his departure, Henry gave Harington a ring, presumably the one with which he sealed many of his letters, inscribed with the motto cui vita et mors [whose life and death].
Following the death of his father in 1613, Harington contracted smallpox in February 1614 and died at Kew on the night of 26-7 Feb. 1614.
