Della Porta has
long been regarded as the inventor of the
|
|
|
camera obscura
because his description of the device has
|
|
|
received much
publicity, as did his camera obscura shows, but
|
|
he was not the
true “inventor”.

In fact there
exists an earlier published description of the
|
|
|
camera obscura
- a translation of Vitruvius's “Treatise On
|
|
|
Architecture”
(1521) by Caesare Caesariano (1483-1543).

It is said that
Della Porta made a huge "camera" in which he
|
|
|
seated his
guests, having arranged for a group of actors to
|
|
|
perform outside
so that the visitors could observe the images
|
|
|
on the wall.
The story goes, however, that the sight of up-side
|
|
down performing
images was too much for the visitors; they
|
|
|
panicked and
fled, and Battista was later brought to court on
|
|
|
a charge of sorcery!
