Rediadis therefore proposed that the Mechanism’s gears served the same purpose as the stereographic mapping on conventional astrolabes; that is, they mechanically translated an observed altitude of the Sun or a star into angles displayed by pointers that represented the positional and temporal data that the ancient navigator required. Rediadis did not try to show how a system of gears could convert an altitude angle into, say, the time of day. Generally speaking, one is struck by how little his interpretation of the Mechanism’s purpose depended on his detailed observations of the fragments and his erroneous attempt to fit the fragments together.
If this “slab” was a part of the Mechanism (we may as well give it the dignity of a capital letter from now on), and there really does not seem to be another plausible candidate, the absence of any mention of wheels or gears is striking. When the fragments came to notice in 1902, the gears were as obvious, and as obviously interesting, as the inscription. ) It would seem, therefore, that the object as brought out of the sea had a different appearance; it was likely an aggregate comprising several of the pieces as they were later known, and the mechanical components were still hidden inside.
