I'll tell you what I *thought* it meant, which is absolutely wrong.
I was thinking Lestat would help Memnoch in part by having Dora
start a new religious movement based on those books. Based on the
sensuality Memnoch and Lestat loved so much.
Maybe they were there to indicate a human perspective of things.
After Memnoch slept with the outcast woman, he thought that was
the best way for humans. Sensuality. Pleasure. Without the Wynken
de Wilde books, it might have come across as these outsiders (Memnoch
and Lestat) saying "yeah, this is how it should be; too bad they can't
see this." But they have. Wynken de Wilde has. Roger has.
Mabye they were there for Dora to reject.
Maybe they were there to give Roger his own (pure or impure?) vision. To
give him substance.
Maybe they were there for Lestat to turn to to recover.
I'm clueless, actually. I think this is one of those questions that
has been answered well before, but months ago.
