What is "al-adami"

ʿAbū ʿAlī al‐Ḥusayn ibn Muḥammad al‐Ādamī (flourished in Baghdad, c. 925) was a maker of scientific instruments who wrote an extant work on vertical sundials. According to al-Biruni, al-Adami was the first to construct a "disc of eclipses", an instrument which demonstrates solar and lunar eclipses.

He should not be confused with his son Ibn al-Adami.
