On the right side of Raphael's School of Athens are two figures representing geography and astronomy. One, a young man with his back to the viewer wearing a crown and holding a terrestrial globe, is Ptolemy, and the other, an older bearded man holding a celestial globe, is Hipparchus. (Following Vasari, who also confuses the two figures, art historians usually identify the latter figure as "Zoroaster", but historians of astronomy know better.) It is not surprising that Ptolemy should hold a… 
An astronomical analysis of Hipparchus' Commentaries
Hipparchus is considered the greatest astronomer of antiquity. However, his fame is due, more than to what he has done, or said, or written, to what the scientists of some generation or of a few
Mapping the stars on the revolving sphere and reckoning time: star catalogues, astronomical popularization, and practical functions
Abstract Among the astronomical texts devoted (in various ways) to the description/explanation of the stars and their phenomena, the sources allow us to identify a somehow ‘specific textual current’
Rounding numbers: Ptolemy’s calculation of the Earth–Sun distance
In this article, I analyze the coincidence of the prediction of the Earth–Sun distance carried out by Ptolemy in his Almagest and the one he carried out, with another method, in the Planetary
Dating the Almagest Star Catalogue Using Proper Motions: A Reconsideration
When considering star catalogues, either modem or ancient, it is useful to distinguish between the dates of the actual star position measurements, which might range over many months or even years,
The Investigation of Stars, Star Clusters and Nebulae in 'Abd al-Raḥmān al-Ṣūfī’s Book of the Fixed Stars
'Abd al-Raḥmān al-Ṣūfī (AD 903–986) is justly famous for his Book of the Fixed Stars. This is an outstanding Medieval treatise on astronomy that was written in AD 964. This work was developed from
’Abd al-Raḥmān al-Ṣūfī’s 3-Step Magnitude System
'Abd al-Raḥmān al-ḥūfī’s Book of the Fixed Stars dates from around AD 964 and is one of the most important medieval Arabic treatises on astronomy. In this paper we begin with a very brief
The Measurement Method of the Almagest Stars
I suggest that the correct standard model of early Greek stellar astronomy is A. Someone, perhaps Hipparchus, measured a fairly complete star catalog in equatorial coordinates. B. That catalog was

On the Origin of the Ptolemaic Star Catalogue: Part 1
The origin of the catalogue of stars found in Books 7 and 8 of Ptolemy's Almagest is a problem that has long vexed both astronomers and historians of science. Ptolemy says rather plainly that he
An Analysis of Errors in the Star Catalogues of Ptolemy and Ulugh Beg
The main peculiarity of Ptolemy's catalogue is the mean systematic error in the longitudes of the stars exceeding 1 • Many astronomers, in a European tradition going back to Tycho Brahe, I have
Ptolemy's Catalogue of Stars
JUST forty years ago the late Prof. Peters, of Clinton, New York, and Mr. Knobel began independently, and without either of them knowing of the other's work, to investigate the Catalogue of Stars in
Various tests are applied to Claudius Ptolemy's long-suspect claim that he himself observed the more than 1000 objects in the Ancient Star Catalog. An obvious consequence of observing under the

Observing with the Armillary Astrolabe
In this paper I investigate the merits and limitations of the armillary astrolabe,' which served for direct observations of the ecliptic longitudes and latitudes of the heavenly bodies from Antiquity
