Abstract

This article surveys surviving evidence for the determination of geographic longitude in Latin Europe in the period between 1100 and 1300. Special consideration is given to the different types of sources that preserve longitude estimates as well as to the techniques that were used in establishing them. While the method of inferring longitude differences from eclipse times was evidently in use as early as the mid-twelfth century, it remains doubtful that it can account for most of the preserved longitudes. An analysis of 89 different estimates for 30 European cities indicates a high degree of accuracy among the longitudes of English cities and a conspicuous displacement eastward (by 5°–7;30°) shared by most longitudes of cities in Italy and France. In both cases, the data suggest a high level of interdependence between estimates for different cities in the same geographic region, although the means by which these estimates were arrived at remain insufficiently known.

十二和十三世纪拉丁欧洲的地理经度
本文调查了 1100 年至 1300 年期间拉丁美洲确定地理经度的现存证据。文章特别考虑了保存经度估算的不同类型的资料来源,以及确定经度估算所使用的技术。虽然根据日食时间推断经度差异的方法显然早在 12 世纪中叶就已开始使用,但这种方法能否解释大部分保存下来的经度仍然值得怀疑。对欧洲 30 个城市的 89 个不同估计值的分析表明,英国城市的经度具有很高的准确性,而意大利和法国大多数城市的经度都有明显的向东偏移(5°-7;30°)。在这两种情况下,数据表明同一地理区域内不同城市的估计值之间具有高度的相互依存性,尽管这些估计值是通过何种方式得出的仍不为人所知。

期刊介绍: The Archive for History of Exact Sciences casts light upon the conceptual groundwork of the sciences by analyzing the historical course of rigorous quantitative thought and the precise theory of nature in the fields of mathematics, physics, technical chemistry, computer science, astronomy, and the biological sciences, embracing as well their connections to experiment. This journal nourishes historical research meeting the standards of the mathematical sciences. Its aim is to give rapid and full publication to writings of exceptional depth, scope, and permanence.
