Although it was about 10 years ago, I recall that there was a graduate student
named Ann Geneva at SUNY-Stony Brook, who was doing her dissertation in history
on the role of astrologers in 17th century English politics. She may well have
done some work on prophets, prophecies and prophetic texts during the course of
her research.
