An Early Witness of Alfonsine Astronomy: The London Tables for 1336

摘要

In the 1320s, a group of astronomers in Paris recast the Alfonsine Tables composed in Toledo in about 1272 under the patronage of Alfonso X, king of Castile and Leon. The tables compiled in Paris by a first generation of Alfonsine astronomers, including John Vimond, John of Murs, and John of Ligneres, reached England, and were disseminated all over Europe, progressively becoming the main tool in computational astronomy. In this paper, we focus on an anonymous set that seems to be the earliest evidence of the Parisian Alfonsine Tables in England.
