This is the crux of the message. Do we agree with
this? (I do not know
which illustration(s) is/are meant).

Agreed.

That was 1600 but I don't know if that makes any
difference in this context.

Anyway, even if the illustration referred to has a Sun
in the centre, I am
not at all sure that that should imply belief in a
sun-centred solar system.
In fact, quite a few other illustrations in the VMs
have the Sun and Moon
in similar 'positions', i.e. at top and bottom of
pages. This would be
evidence of an Earth-centred system, which does not
help us much because
the Sun-centred system was not universally accepted
until much later.

Cheers, Rene
