Journal for the History of Astronomy

Planetary Expansion-Contraction Difference ( Ying suo cha盈縮差) in ancient Chinese planetary theory was mainly used to correct non-uniform motion of the planet. The independent variable of planetary Expansion-Contraction Difference is the Argument Degree Entry ( Ru li du入曆度) of the planet, which is related to the Limit Degree ( Xian du限度) in the table of planetary Grades of Motion ( Wu xing dong tai biao五星動態表). In this paper, we mainly discuss astronomical meanings of the Expansion-Contraction Difference and Limit Degree of the outer planets. First, we go through the historical development of the astronomical meaning of planetary Expansion-Contraction Difference and Limit Degree in ancient Chinese planetary theory. Then, we reconstruct a new mathematical model of Expansion-Contraction Difference for the outer planets. Finally, we discuss the errors in the longitude of the outer planets in the Era Epoch System ( Ji yuan li紀元曆, A.D.1106) of Northern Song北宋Dynasty (A.D.960–1127) using different mathematical models of planetary Expansion-Contraction Difference and Limit Degree. The result shows that the Expansion-Contraction Difference and Limit Degree of the outer planets in the Era Epoch System and other astronomical systems should be the results of continuous refinement by astronomers on the basis of long-term actual observations and measurements, and their combination was a strong guarantee to ensure that the Era Epoch System is comparable to the Copernican system in the calculations of the planetary position.

Research on the Expansion-Contraction Difference and Limit Degree in ancient Chinese planetary theory: The case of outer planets

古代中国行星理论中的膨胀-收缩差异与极限程度研究：以太阳系外行星为例

The Graha-lāghava (“Easy [computation] of the planets”; epoch date 1520), is an astronomical handbook, authored by Gaṇeśa Daivajña (b. 1507 CE) of Nandigrāma. This work became one of the most popular astronomical texts of the second millennium in India and gave rise to a new astronomical school of parameters, eponymously known as the “Gaṇeśa-pakṣa.” We analyze the first of the 16 chapters that make up this work, which covers planetary mean positions and velocities, providing a translation and technical commentary of the text. In our exposition, we also invoke two substantial commentaries on this work that were composed in the 17th-century by brothers Mallāri and Viśvanātha, which help clarify and contextualize Gaṇeśa’s contributions. An Appendix to the online edition of the Journal gives the Sanskrit text of the quoted passages.

This paper is a study of the visual characteristics of the medieval manuscript diagrams found in Theodosios’ Spherics. It provides a new taxonomy of eight types of diagrams found in the manuscript sources, and examines the way in which geometric information is encoded in the manuscript diagrams using a number of visual encodings. It then argues that these diagrams can be used to address ongoing research debates about whether the striking visual characteristics of medieval diagrams in mathematical texts are the result of deliberate choices by the premodern authors, the result of accidents of transmission, or both. Along the way, the paper identifies a further type of transmission error that is prevalent in the medieval transmission of mathematical diagrams.

狄奥多西奥斯《球面几何》手稿图解

Two Latin sources from the years around 1300 (John of Sicily’s commentary on the canons to the Toledan tables and a parchment slip documenting the astronomical activities and observations of Alard of Diest) contain brief references suggesting that Parisian scholars of this period had access to a set of astronomical tables for Tunis known as tabulae Benesac. According to the argument developed in this article, the tables in question probably corresponded to a Maghribī zīj originally created by Ibn Isḥāq al-Tūnisī in c.1222. The article goes on to discuss the possible channels of transmission that could have brought these tables to Paris as well as the potential implications of this finding for the history of Latin astronomy in the late 13th and early 14th century. Attention is also drawn to the presence of eclipse-related material from the Muqtabas zīj by Ibn al-Kammād in a Northern French manuscript of the second half of the 13th century, which was independently translated from the Arabic and accordingly does not derive from the well-known translation by John of Dumpno (Palermo, 1260).
