"Poor

feeling
against
Your
Excellency,
for
Magini
has
written
three
letters,

were
confirmed
by

men

Bologna,
to
give
effect

It
was
probably
this
letter
which
lead
Prof.
de
Santillana
to
the
erroneous
statement:
"It
took
even
Kepler,
always
generous
and
open-minded,
a
whole
five
months
before
rallying
to
the
cause
of
the
telescope...
His
first
Dissertaro
cure
Nuncio
sidereo,
of
April,
1610,
is
full
of
reservations.''
(

the
Great
World
Systems,

p.

n.)
Kepler's
reservations
referred,
as
we
saw,
to
the
priority
of
the
invention
of
the
telescope,
not
to
Galileo's
discoveries
with
it.

The

sometimes
erroneously
referred
to
as
"Harmonices",
as
if
the
"s"
stood
for
the
plural,

it
stands,
of
course,
for
the
genitive.
