A recent paper' has discussed the solar and lunar kinematic models described by the fourteenth-century Damascene astronomer known as Ibn al-Sht the planet is at the terminal point of the last. Thus Ibn al-Shatir abandoned the eccentric orbits and the equants which so strongly characterize the work of Ptolemy. For all the outer planets and Venus the number of component vectors is the same, and the models differ only in the lengths and angular velocities of the components. It is therefore… 

The Planetary Theory of François Viète 1. The Fundamental Planetary Models

The mathematical techniques of planetary theory carefully explained and used by Ptolemy were still nearly unchanged when Copernicus had completed De revolutionibus some 1400 years later. Many of

Holding or Breaking with Ptolemy's Generalization: Considerations about the Motion of the Planetary Apsidal Lines in Medieval Islamic Astronomy

TLDR
In medieval Islamic astronomy, the Ptolemaic generalization in the case of the equality of the motions of the apogees remained untouchable, despite the notable development of planetary astronomy, in both theoretical and observational aspects, in the late Islamic period.

An analysis of Ibn al-Shāṭir’s star table

Ibn al-Shāṭir’s (1306–1375/1376 AD) star table in his Jadīd zīj, comprising of the equatorial coordinates and magnitudes of 89 stars, is edited and analyzed in this paper on the basis of the extant

Aristotelian Planetary Theory in the Renaissance: Giovanni Battista Amico's Homocentric Spheres

In 1536 a young man of 23, Giovanni Battista Amico, published a treatise on planetary theory called "On the Motions of the Heavenly Bodies according to Peripatetic Principles without Eccentrics or

VÉNUS SELON IBN AL-ŠĀṬIR

Abstract We attempt to grasp the mathematics behind the planetary theories of the Syrian astronomer Ibn al-Šāṭir (1304–1375) in his treatise Nihāyat al-Sūl. Following the astronomers of the Marāgha

Algol anomaly or careful observations of its brightness? The values recorded for the magnitude of Algol in the medieval astronomical corpus

The historical evidence from the past two millennia show two problems concerning the star Algol (β Per): First, a critical variation in its brightness from a magnitude m ~ 2 in (1) Ptolemy’s Almagest

Copernicus's Path to His Cosmology: An Attempted Reconstruction

Copernicus's Commentariolus begins by complaining that, while the ancients had wanted astronomy to obey the principle of uniform motion in perfect circles, Ptolemy's equant violates this principle.

Rolling Circles of Motions: Yesterday and Today

In this chapter, we give a short historical survey of basic events which had happened during the development of models depend on a rolling circles around circles. The first seeds of these models can
