Until the late 15th century, knowledge of Ptolemy’s Almagest in the Latin West was constituted by Gerard of Cremona’s translation from Arabic into Latin. The text of Gerard’s translation has been examined carefully and its dependence on two different Arabic versions is well studied. However, the tables of Gerard’s Latin Almagest have not been scrutinized, and the relation to their Arabic or Greek counterparts has not been examined. In this article, I will analyze the historical mathematical structure of tables in Gerard’s Latin Almagest translated from the Arabic in comparison to their Arabic and Greek precursors. While Gerard’s text has proved to be a faithful translation from Arabic templates, some of the tables will turn out to be different. Fundamental tables for, for example, the chord interpolation values, declination, and rising times appear to have been recomputed in order to match Ptolemy’s proofs and paradigm computations, which, in contrast, generally diverge in both Greek and Arabic tradition with the tables. It remains unclear if Gerard himself or someone in his company recalculated these tables and thus deliberately aimed to correct the ancient classic of astronomy. By a systematic analysis of these tables, I intend to provide a novel perspective on the medieval transmission and translation of knowledge, its cross-cultural exchange, and especially the practice of Gerard of Cremona and his collaborator(s).
Adam Elsheimer's The Flight into Egypt (1609) has triggered a longstanding debate among art historians. For the last five decades, Elsheimer's novel naturalistic representation of the night sky in his painting on copper has been linked to Galileo's telescopic observations. To explain the astronomical details of this painting, scholars have contended that Elsheimer observed, before Galileo, the night sky with one of the first telescopes available in Rome. So far, the debate has lacked input from the history of astral science. This article presents a case study that examines the relationship between the visual arts and astronomical knowledge. It offers a contextualized analysis of the technical details of the artwork within the prevailing astronomical knowledgebefore the appearance of Galileo's Sidereus Nuncius-and frames it within the network of and debates among prominent figures of Galileo's and Elsheimer's time. It proposes a revisionist interpretation of Elsheimer's most famous artwork based on an analysis of the technical and cultural practices of discerning and imagining the night sky around 1600.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
