Kelman's job, though he might not put it this way,
was to write a grimoire- a Kabbalistic story bible.
Mantua was in fact
the most important city for the study of Jewish culture, where Kabbalistic schools flourished, together
with Jewish theatre and poetry, despite recurring persecutions.
As well as other Kabbalistic sources, describe the structure of the upper worlds,
how they descend and how our universe, with everything that's in it, came into existence.
