Jalal al-Din Yazdi

Jalal al-Din Mohammad ibn Abdollah Yazdi (Persian: جلال‌الدین محمد بن عبدالله یزدی; died 1618), also known as Jalal al-Din Monajjem Yazdi (جلال‌الدین منجم یزدی), was a Safavid astrologer (monajjem) and chronicler of Persian origin.

His chronicle, the Roozname-ye Molla Jalal (also referred to as Tarikh-e Abbasi), covers Safavid history from 1576 to 1611.

It deals with a period spanning from the final year of the reign of Shah ("King") Tahmasp I (r. 1524–1576) to the penultimate decade of the reign of Shah Abbas the Great (also known as Abbas I; r. 1588–1629).

Born at an unknown date, Yazdi's family originated from the city of Yazd.

One of his sons, Kamal, became court astrologer in the final years of the reign of Abbas I and continued to occupy this post until the reign of Shah Abbas II (r. 1642–1666).
