Talk:Francesco Lana de Terzi

Untitled

I google translated from the German Wikipedia, and tried my best to clean up the grammar so that it makes sense, but the following section on his proposed writing system for the blind is very rough, and I'd appreciate input/improvement:

Ideas on writing for the blind

Also in his book Prodromo, there's a chapter entitled the way in which the blind can learn to write, but also by a cipher and the understanding of it, the answers in the same ciphers can hide secrets: Franceso Lana de Terzi considered different possibilities, for example a cord or an attached writing, as well as a cryptogram. This cryptogram would consist of a flat writing, with which the letters would be translated into a system of lines and points. These lines and points would be tactile, since they show raised structures on the paper. It recommended beyond that that blind people, if they wanted to write the writing of the sighted, to use strings or wires, so that they could keep the lines. Thus he is the inventor of the “hand leaders”, that are used this very day - if in modified form -, if a blind individual writes a short report for the sighted or a signature upon delivery.
