Seven pages of prose ‘argument’ (plot summaries for each book) are now included 

Second edition of Paradise Lost is published with the new title Paradise Lost. A Poem in Twelve Books

Third edition of Paradise Lost

Fourth edition of Paradise Lost: the first illustrated edition, entitled Paradise lost. A poem in twelve books...The fourth edition, adorn'd with sculptures (London: Richard Bently & Jacob Tonson, 1688).

This lavish edition's illustrations are the work of at least three individual artists, including John Baptist de Medina and Bernard Lens.

The first full Latin translation of Paradise Lost is published, in a volume entitled Paraphrasis poetica in tria Johannis Miltoni, also including Paradise Regained and Samson Agonistes; the translation is by William Hog. 

The ‘emended’ edition of Paradise Lost by Richard Bentley is published. 

Here is an example of Bentley's notes, 'correcting' passages from Book 5. The Christ's College copy contains manuscript annotations (right of page) by the eighteenth-century English poet William Cowper, who here pours scorn on Bentley's re-interpretation.

William Blake first sketches illustrations to Paradise Lost in his notebook, which later become watercolours

John Martin’s mezzotint illustrations are first used in an edition of Paradise Lost 

Milton’s works were popular throughout the Victorian period, which saw many reprints and publications of his work. The Brontë sisters took inspiration from Milton’s work, for example. 

Throughout the twentieth and twenty-first centuries, there have been many scholarly editions of Paradise Lost, typically with annotations to aid the reader.

The most useful and extensively annotated modern edition is probably Alastair Fowler's Longman edition, described on its cover as 'one of the great scholarly books of modern times'.

Another example is a 2005 edition with reproductions of the first illustrations from 1688 and an introduction by Philip Pullman, whose His Dark Materials series is influenced by Paradise Lost.
