Mulla Mahmud Jaunpuri (Persian: ملّا محمود جونپوری; 1606–1651) was an important Indian natural philosopher and astronomer of the 17th century under the reign of Shah Jahan.
He was from a family of Hindu astrologers who converted to Islam under the patronage of a Sufi saint during Akbar rule.
[1] Book II of his classic Shams-e-Bazeghi is on theoretical astronomy, where he raises doubts about the Ptolemaic system.
He discusses various views on the spots of the Moon, refutes them, and advances his own theory that these are some tiny bodies on which the Sun's light does not reflect.
In this treatise, he refuted the doctrine of atemporal origination (huduth-e-dahri) proposed by the Iranian philosopher Mir Damad.
