Of aristocratic descent, his family bore the surname of Fynes for five generations until his father, the Revd Preb. Charles Fynes, resumed the ancient noble name of Clinton in 1821. His younger brother Clinton Fynes ClintonMP is ancestor of the present Earl of Lincoln.[1]
His reading was methodical (see Literary Remains of H. Fynes Clinton), whilst his Fasti, on classical chronology, has required correction on the basis of later research.
Fynes Clinton's major works are:
Fasti Hellenici, the Civil and Literary Chronology of Greece from the 55th to the 124th Olympiad (1824–1851), including dissertations on points of Greek history and Scriptural chronology; and
Fasti Romani, the Civil and Literary Chronology of Rome and Constantinople from the Death of Augustus to the Death of Heraclius (1845–1850).
In 1851 and 1853 respectively he published epitomes of the above. The Literary Remains of H. Fynes Clinton (the first part of which contains an autobiography written in 1818) were edited by Clinton Fynes Clinton in 1854.
