approach. Samuel Warren, in his Legal Studies, 3rd ed. 1854 (i. 235–6, 349), highly praises his historical work. But he ludicrously overestimated all his performances, and his claim to have written the best history of Rome in any language, or to be the first to justly value Virgil and Sallust, could not be admitted by his friends. During the last years of his life he received a pension from the civil list. He died at Erith, Kent, on Nov 4, 1872. Besides the works already mentioned Keightley was author of The Crusaders, or Scenes, Events, and Characters from the times of the Crusaders (1834). His Secret Societies of the Middle Ages (Library of Entertaining Knowledge 1837) was initially published anonymously, and against his wish, and later reprinted in 1848. Literary criticisms Keightley edited Virgil's Bucolics and Georgics (1847), which was prefigured by his Notes on the Bucolics and Georgics of Virgil with Excursus, terms of Husbandry, and a Flora Virgiliana, (1846). Other Latin classics he edited were Horace, Satires and Epistles (1848), Ovid, Fasti (1848), and Sallust, Catilina and Jugurtha (1849). Milton studies Keightley produced an annotated edition of Milton (2 vols. 1859) as well as his critical biography Account of the Life, Opinions, and Writings of John Milton, with an Introduction to Paradise Lost (1855). His nuggets of insight have been occasionally invoked, compared, and contradicted in studies into the 20th century and beyond. He is listed among the "distinguished file" in one survey of past commentaries on Milton, going back three centuries (). Appreciation of allusions in Milton's poems require familiarity with classical Greco-Roman mythology and epics; to borrow the words of an American contemporary Thomas Bulfinch: "Milton abounds in .. allusions" to classical mythology, and especially "scattered profusely" throughout Milton's Paradise Lost. Keightley was one annotator who meticulously tracked Milton's mythological sources. Some of Keightley's flawed commentary have been pointed out. He argued that Milton erred when he spoke of "Titan, Heaven's first-born," there being no single divine being named Titan, only a race of titans. Though that may be so according to the genealogy laid out by Hesiod's Theogony, it has been pointed out that Milton could well have used alternate sources, such as Lactantius's Divinae Institutiones ("Divine Institutes"), which quotes Ennius to the effect that Uranus had two sons, Titan and Saturn. Likewise regarding Milton's angelology, Keightley had made some correct observations, but he had
