Méric Casaubon published A True & Faithful Relation in 1659, editing records of John Dee's alleged communications with spirits. The book exposed Elizabethan angel magic to a Restoration-era readership. It appeared in a culture fascinated by science, occult knowledge and religious suspicion.

Dee's diaries influenced the literary imagination of magic, language and hidden worlds. Casaubon's edition shows how private visionary records could become public prose, feeding later poetry and drama about forbidden knowledge.
