In addition to Blake's notes on the painting, a letter written to Ozias Humphrey provides a description of the various images within an earlier design of the Last Judgement.
[2] These include an 1808 watercolour version made for Elizabeth Ilive, wife of George Wyndham, 3rd Earl of Egremont, that was displayed at their Petworth House.
[2] Other editions included watercolours made for Thomas Butts in 1806, 1807, and 1809, one for John Flaxman in 1806 (lost), and an 1809 unsold version in tempera.
Notes for what Blake planned to write for the works A Vision of the Last Judgement and Public Address survived.
[5] Blake, in his notes to A Vision of the Last Judgement, describes how his design is to work: "If the Spectator could Enter into these Images in his Imagination approaching them on the Fiery Chariot of his Contemplative Thought [...] then would he arise from his Grave".
[6] He relies on the word representation frequently in the work, and he tries to represent action in a visible manner that distances his depiction of the apocalypse from a traditional version that disguises the various components of an apocalyptic vision.
This creates a layer of representation that separates the audience from the apocalyptic experience, which undermines the concept of apocalypse as both mysterious and directly experienced.
[10] This idea is connected to views of David Hartley of the "pure disinterested love of God", and appears in other works by Blake, including his Jerusalem.
[11] Also, Blake's Milton describes the process that an individual goes through during an apocalypse, which includes having to confront their errors and their flaws.
[12] On the details in the painting, Blake claimed that each component had a specific meaning that provides an allegory-like dimension to the work.
