It
is true that people used to read aloud at that time or, at least, by
moving their tongues. And it is also true that the first person known
for reading silently was Saint Ambrose. We know that thanks to Saint
Augustine in his “ Confessions”. I heard about that many years
ago in an article by Borges, and this image was etched in my memory.
It seemed wonderful to me that someone had invented silent
reading
suddenly
and so late , especially
because
it implies something unbelievable: apparently neither Plato nor
Seneca, for instance, had never known how to read in low voice.
Somehow I did not really believe it. Seneca was said to have read all
the books in Rome with a water-filled balloon. Since glasses did not
exist, he used that gadget as lens. I do not think that he could even
do it by reading aloud.
The first glasses did not seem to appear until around the 13th century . Before that, people used to get by quite well with home-made solutions, like -Seneca´s or the so-called “reading stones” which managed to magnify the size of the letters. In my view, the invention of glasses is, together with that of the toilet, one of the things that make us real civilized human beings.
