Table type definition

Tables are classified according to different types. These different types correspond to the specific steps in astronomical computationas organised by historical actors. In modern terms, these types correspond to distinct classes of mathematical functions which express a portion of an underlying astronomical theory.

Eighth sphere definition

Imaginary sphere carrying all the constellations of the fixed stars, observed to move with respect to the referential of the ecliptic circle, in particular to the position of the Sun at the equinoxes.
