Name of tha book written by al battani?

Al-Battani didn't write a single book with a specific title. His most famous work was "Kitab al-Zij" (Book of Astronomical Tables), which was later translated into Latin as "De Motu Stellarum" (On the Motion of the Stars).

While "Kitab al-Zij" is the most widely recognized, it's important to note that this wasn't his only work. Al-Battani was a prolific astronomer who wrote other treatises on astronomy, including:

* "On the Heights of the Stars"

* "On the Determination of the Meridian"

* "On the Sundial"

However, "Kitab al-Zij" is considered his magnum opus and remains a crucial resource for studying the history of astronomy.
