Al-Wabkanawi

Shams al-Munajjim Muhammad ibn Ali al-Wabkanawi was a 14th-century Persian astronomer. He is the author of an important zij known as "al‐Zīj al‐muḥaqqaq". Presumably he hailed from Wābkana, Bukhara. Not much is known about his life. His zij is extant in four manuscripts. His book is written in Persian language, even though its title is Arabic. Another book by him, known as "Kitāb‐i maʿrifat‐i usṭurlāb‐i shamālī" is also extant and is written in Persian language.
