Giovanni Battista della Porta (contd.)
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!
