Astral sciences

The following aspects of ancient Mesopotamian astronomy are treated in the articles on astral sciences:

- Introduction to Babylonian Astronomy

- Omens from celestial phenomena

- Theoretical texts, schematic

- Observations

- Procedure texts, mathematical

- Table texts

- “Astrology”
From a modern point of view, it can be disputed whether celestial omens should be included among sources of Babylonian astronomy. For the Ancients the modern difference between astronomy and astrology certainly did not exist, as can be seen, e. g., from the inclusion of lunar tables in Tablet XIV of the omen collection Enūma Anu Enlil (see the article on Schematic astronomy).
