The Commentary, the first full version on Paradise Lost since the Richardsons' in 1734, combines numerous resources with features used for the first time. It includes the best commentary from "Annotations" like Patrick Hume's (1695), to the variorum editions of Newton (1749) and Todd (1801 - 42), and the modern professional editions culminating in Alastair Fowler's (1968). Other elements include an essay on the early pre-annotative criticism from 1668, including Marvell, Dryden, Dennis, and others, copious use of the OED, numerous cross-references to Milton's other works and passages in Paradise Lost, fourteen excurses and other contributions by the present editors. This Commentary is itself a research library for Paradise Lost. It uniquely presents biblical, classical, and vernacular citations: the ultimate rather than a more recent source is cited, so dating the comment, every cited passage is quoted, and every question is in English. Only a text of the poem is required.
