THE FACE OF THE SOUL
This is a Volvelle, it is a round paper device
with concentric rotating parts that, when
manipulated, show a new composition/
information.
In the Middle Ages it was used as a
calculation tool in astronomy (to determine
the position of the sun or moon, or the day
of Easter Sunday). That is why it is, by some,
appointed as the 1st (analog) computer!
