VMs: Re: Mediaeval book written entirely in cipher

[Jorge Stolfi <stolfi@xxxxxxxxxxxxx>]

I don't recall whether Nick already posted this one. It includes the
same image of the devil lantern (perhaps just a bit clearer?), and
another one of a medieval "virtual reality environment" (no cipher
text, though):

      1.the castellum umbrarum , castle of shadows, designed by the
      venetian engineer Giovanni Fontana in his manuscript (bellicorum
      instrumentum liber 1420, cited in S. Y. Edgerton's book The
      heritage of Giotto's geometry, art and science on the eve of the
      scientific revolution 1991), which can be best described as a
      Pre-CAVE installation.

      It describes a room with walls composed of folded translucent
      parchments lighted from behind, creating therefore an
      environment of moving images. He also designed some kind of
      magic lantern to project on walls life-size images of devils or
      beasts. The use of projected images on walls was later detailed
      by one of the major figure of baroque humanism, the Jesuit
      father Athanasius Kircher "master of a thousand arts" in Ars
      magna luce et umbrae 1646.

All the best,

PS. "Monaco" in the previous post was of course Munich
("Monaco di Baviera") not Monaco ("Principato di Monaco").
