Some variants in the materials related to the planetary latitudes, including
computational procedures, underlying parameters, numerical tables, and so on, may
be addressed in the corpus of the astronomical tables preserved from the medieval
Islamic period (zıj literature), which have already been classified comprehensively by
Van Dalen (Current perspectives in the history of science in East Asia. Seoul National
University Press, Seoul, pp 316–329, 1999). Of these, the new values obtained for the
planetary inclinations and the longitude of their ascending nodes might have something
to do with actual observations in the period in question, which are the main concern
of this paper. The paper is in the following sections. In the first section, Ptolemy’s latitude
models and their reception in Islamic astronomy are briefly reviewed. In the next
section, the medieval non-Ptolemaic values for the inclinations and the longitudes of
the nodal lines are introduced. The paper ends with the discussion and some concluding
remarks. The derivation of the underlying inclination values from the medieval
planetary latitude tables and determining the accuracy of the tables are postponed to
“Appendix” in the end of the paper.
