John Dee and Edward Kelly had intercourse with her in turn. When it was done John Dee went back to his books, for he was never comfortable with much that was not a book. Edward Kelley fell asleep. They had forgotten me and I had not minded.

'I think these things are the magick of our own minds, not visitations from elsewhere.'
'Then our minds must be multitudes indeed.'
'I think we are worlds compressed into human form.'
