Greek astronomical calendars I. The parapegma of Euctemon

Summary

In view of the striking similarities noted in the subsection A, B, C we are bound to conclude that Euctemon was influenced by Babylonian astronomy. However, his parapegma was not just a translation of a Babylonian text: it was an improvement in many respects. His dates of annual risings and settings were more accurate than the Babylonian dates. In most cases he recorded true risings, or he recorded both the true and the visible phaenomena. This distinction is not made in the text MUL APIN.
