ABSTRACT There has been much debate surrounding the way in which Ptolemy handled the observations that are behind his planetary models. This article aims at presenting an interesting case of manipulation of observational data within the epistemological frame of what we may call Ptolemy’s philosophy of knowledge. It deals with an interesting case from the Almagest, that of the determination of the longitudes of the apogee and perigee of Venus’s deferent, and shows that the selections and adjustments Ptolemy carried out in order to obtain the needed results are nothing but an analogous application of the epistemological doctrines expressed in his On the Kriterion and in his Harmonics.

调节金星：最大伸长率在托勒密和托勒密知识理论中的使用

摘要关于托勒密如何处理他的行星模型背后的观测结果的方式，存在着许多争论。本文旨在提出一个有趣的案例，即在我们称之为托勒密知识哲学的认识论框架内操纵观测数据。它处理了来自Almagest的一个有趣案例，即确定金星的远地点的近地点和近地点的经度，并表明为获得所需结果而进行的选择和调整托勒密只是与之相似的应用。他的《论立论》和《谐波》中表达的认识论学说。
