Early Babylonian Astronomy: Observations and Numerical Fits
摘要
One goal of this paper is to illustrate what we can learn about the development of Babylonian lunar astronomy by controlling the precision of the astronomical numerical schemes in EAE 14 and MUL.APIN against nature. Another goal is to show that the schemes for day lengths found in the advanced Mathematical (ACT) Texts most likely origin in the observation of ŠÚ+NA and ME+GE6, which measure the daily delay of the setting and rising full Moon, respectively. These time differences have been regularly observed and recorded since the seventh century BCE. The daily retardation of the Moon was already treated in EAE and MUL.APIN.
