Presentation

This session examines some of the first works on the history of mathematics and astral sciences in Mesopotamia, in the context of professionalization of history of science by the late 19th century and early 20th century. In which intellectual context and in which milieus did the interest for cuneiform mathematical and astronomical sources emerge? How did the different protagonists of the early historiography of cuneiform mathematics and astral sciences approach these sources? Which assumptions did they bring to their study? Which topics did they favor?

*Chaldean/Babylonian mathematics according to Hankel and Cantor*

**Abstract** – At a time when little was excavated and known in Assyriology, Hankel and Cantor, interested in the history of mathematics, set out to write about mathematics of the “Chaldeans” or “Babylonians”. What were their sources? How did they use them? What kind of mathematics were they interested in? How did they represent these cultures, in what terms: linguistic, geographical, racial, and/or ethnical?

*Abraham Sachs and the History of Babylonian science***
Abstract **– The meeting between Abraham Sachs and Otto Neugebauer which led to Sachs taking up a position at Brown first as Neugebauer’s assistant and then as a fellow professor in the Department for the History of Mathematics marks a crucial turning point in the study of the Babylonian exact sciences. Although Sachs’s contributions to the field have often been hidden to outsiders by the shadow of Neugebauer, Sachs made significant contributions to the study of Babylonian mathematics and astronomy in his own right. This paper will explore those contributions and compare the work and approach of the philologist-who-learned-science Sachs with those of the mathematician-who-learnt-philology Neugebauer.

*The rediscovery of Babylonian Astronomy: a historiographic narrative*

**Abstract –**In this paper I will discuss the rediscovery of Babylonian mathematical astronomy by the Jesuits J.N. Strassmaier (1846-1920) and J. Epping (1835-1894) and the subsequent more extensive studies by their colleague F.X. Kugler S.J. (1862-1929) in the period 1880 – 1930. This early phase of the study of Babylonian astronomy took place at the Jesuit colleges in Blijenbeek, Exaeten and Valkenburg in the Netherlands. During his career Kugler pioneered virtually every aspect of Babylonian astronomy and he contributed to several disciplines in which Babylonian astronomy played a role. He also became involved in a number of personal and scientific controversies. Well-known is his crusade against Panbabylonism, a school of thought that tried to show that the most important mythologies and world religions originated from an ancient system of astral myths diffused from Babylon. When in the early 1930’s Otto Neugebauer (1899-1990) entered the field of Babylonian mathematical astronomy this pioneering phase had come to an end.

*“Greek” science, “Babylonian” science? A vexata quaestio in the historiography of science*

**Abstract** – My talk will focus on three instances of the reception of cuneiform texts on Mesopotamian science by scholars of ancient Greece. I will begin with Franz Boll’s collaboration (ca. 1900-1922) with assyriologist Carl Bezold on Greek and Mesopotamian astral sciences. I will continue with J.K. Fotheringham’s assessment of « The Indebtedness of Greek to Chaldaean Astronomy » (1928). Finally, this will lead me to the exceptional group of scholars which formed around the journal Quellen und Studien zur Geschichte der Mathematik, Astronomie und Physik (1929-1938), including students of ancient Greek science and philosophy such as Fotheringham, O. Neugebauer, J. Stenzel, O. Toeplitz and O. Becker.
