The Castilian Alfonsine Tables, compiled under the patronage of Alfonso x, were a vehicle for the transmission of this body of knowledge to astronomers north of the Pyrenees, but the details of this transmission remain elusive, in part because only the canons to these tables survive. This chapter builds on studies of a figure that previously had barely been mentioned in the recent literature on medieval astronomy. John Vimond was active in Paris ca. 1320 and his tables have much in common with the Parisian Alfonsine Tables, but differ from them in many significant ways. The exact date of composition of Vimond's tables is not given in the text, but they were probably produced shortly before 1320.Keywords: Castilian Alfonsine Tables; John Vimond; medieval European astronomy; Paris","PeriodicalId":407929,"journal":{"name":"Suhayl.

Its rediscovery brings our knowledge of the activities in that flourishing scientific centre a substantial step further. This type of instrument was previously not known to exist, although sundials based on the same principle are described in Arabic treatises datable to ca. 950 and ca. 1280. It is essentially a mathematical device providing a graphic solution to a problem that was of interest to Muslim astronomers, namely, the determination of the time of day as a function of the solar altitude throughout the year, here specifically for the latitude of Baghdad. The instrument reveals a level of mathematical competence and sophistication that is at first sight astounding. However, with a deeper understanding of the scientific milieu from which it came, it can be seen to be fully within the theoretical competence of the scientists of that environment. Nevertheless, the spectacular accuracy of the engraving of the principal curves on the instrument is completely unexpected. The instrument also features the earliest known solar and calendrical scales from the Islamic East; the origin of these was previously thought to be in the Islamic West.","PeriodicalId":407929,"journal":{"name":"Suhayl.

This is also true of many other medieval mosques. However, now that we have some control over the medieval textual sources relating to the Kaʿba and to the qibla, we can see that in the first two centuries of Islam, and occasionally also long thereafter, astronomical horizon phenomena were used to face the Kaʿba, itself astronomically aligned. From the 9th century onwards, mainly directions based on geographical data and mathematical procedures were used to align mosques towards Mecca. Nevertheless some of the earliest mosques, as in Jerusalem and Damascus, were aligned with pre-Islamic religious edifices or complexes. In the case of the Great Mosque of Cordoba, it was a suburban Roman street-plan, revealed by excavations only some 20 years ago, which defined the qibla-axis of the Mosque, and this happened to be one of the several qibla-directions favoured in al-Andalus. So in medieval terms the Mosque could indeed have been thought to be facing the Kaʿba.","PeriodicalId":407929,"journal":{"name":"Suhayl.

His project produces a new and consistent set of parameters. On the basis of his four documented observations of Mars, carried out in 1264, 1266, 1270, and 1271 AD, he measured the unprecedented values for the radius of the epicycle, the longitude of the apogee, and the mean motion in longitude of the planet and also confirmed that Ptolemy’s value for its eccentricity was correct for his time. This paper presents a detailed, critical account of Muḥyī al-Dīn’s measurements. Using a criterion described below, we compare the accuracy of his values for the structural parameters of Mars with that of other historically important values known for these parameters from medieval Middle Eastern astronomy from the early eighth to the late fifteenth century. Muḥyī al-Dīn attained a higher degree of precision in his theory of Mars established at Maragha than the majority of his predecessors; the results were also more accurate than those established in his earlier zīj written in Damascus in 1258 AD and used in the official astronomical tables produced at the Maragha observatory, the Īlkhānī zīj","PeriodicalId":407929,"journal":{"name":"Suhayl.

It focuses in particular on the role played by the famous orientalist Guillaume Postel (1519-1581) who seems to have studied Arabic astronomical texts dealing with planetary theories and tries to contextualize the marginal notes Postel wrote on the Arabic manuscripts that he had owned. The purpose of this investigation is to demonstrate that the sixteenth century European scientists like Pastel were not in need of Latin translations of Arabic scientific works in order for them to incorporate those works in their own for they could read the original Arabic texts and understand their import, and at times even correct those same texts. Once this interaction between Renaissance Europe and the Islamic world is fully appreciated one could better understand the conditions under which the well documented mathematical works that were first developed in the Islamic world could have been transmitted to people like Copemiclls without having those original Arabic works necessarily translated into Latin.","PeriodicalId":407929,"journal":{"name":"Suhayl.
