Harkness

Harkness frames Dee's angel conversations as a continuation of his natural philosophy rather than a late-career aberration. The Book of Nature is corrupt and decaying, and the angels provide exegetical and restorative tools for reading and healing it.

Uses Prague to show Dee as public prophet, communicator, natural philosopher, and political-religious actor. Reconstructs Dee, Kelley, scryers, household, instruments, revealed books, angels, patrons, and audiences.

Explains how Dee's earlier work prepared the angel conversations: Scripture and Nature as books, Propaedeumata as optical/celestial causation, Monas as symbolic decipherment, and mathematics as mediator.

Shows why angels could function as natural-philosophical mediators. Dee sought pure wisdom through lawful prayer, angelic hierarchy, optical mediation, and ritual discipline.

Places the conversations in apocalyptic culture. Nature, learning, church, and political order seemed to be decaying, making Dee's angelic reform urgent.

Argues that the angels revealed a true cabala of nature grounded in divine/Adamic language, true names, tables, gates, airs, governors, and Enochic material.

Completes the program: after reading nature through cabala, Dee receives restored Adamic alchemy and the medicine of God to heal nature's corruption.

Traces collapse of Dee and Kelley's partnership, Dee's later disappointment, manuscript survival, Casaubon's skeptical framing, and later antiquarian/natural-philosophical interest.
