AbstractAstronomers have always considered the motion of the Moon as highly complicated, and this motion is decisive in determining the circumstances of such critical celestial phenomena as eclipses. Table-makers devoted much ingenuity in trying to find ways to present it in tabular form. In the late Middle Ages, double argument tables provided a smart and compact solution to address this problem satisfactorily, and many tables of this kind were compiled by both Christian and Jewish astronomers. This paper presents multiple examples of the diversity of approaches adopted by compilers of tables who used this powerful tool, and brings to light intellectual interactions among them that are otherwise hidden from view.

矩阵中的中世纪月亮：月球运动的双参数表

摘要 天文学家一直认为月球的运动是高度复杂的，而这种运动对于日食等关键天象的发生情况具有决定性作用。制表师们在试图找到以表格形式呈现它的方法上投入了很多独创性。在中世纪晚期，双参数表提供了一种巧妙而紧凑的解决方案来令人满意地解决这个问题，基督教和犹太天文学家都编制了许多此类表格。本文介绍了使用这一强大工具的表格编制者所采用的各种方法的多个示例，并揭示了他们之间隐藏的智力互动。
