ʿAbū ʿAlī al‐Ḥusayn ibn Muḥammad al‐Ādamī (Arabic: أبو علي الحسين بن محمد الآدمي; flourished in Baghdad c. 925) was a maker of scientific instruments who wrote an extant work on vertical sundials, Techniques, Walls, and the Making of Sundials[1][2] (Kitab takhlTt al-sa v at wa inhiraf al-hTtan wa’l-zilalat wa alTad al-sumut).[3] The manuscript, which is held in the Bibliothèque nationale de France, contains tables that enabled the drawing of lines to show any desired angle of latitude.[1] The surviving copy of al-Adami's 10th century manuscript (Arabe 2506,1 (fols. 1r-62r) dates from the 15th century, which King has suggested was written either by al-Adami or by a contemporary, Sa'id ibn Khafif al-Samarqandi. The tables on folios. 31v–33v were intended to be used in the construction of a vertical sundial.[4]

According to the Iranian polymath al-Biruni, al-Adami was the first to demonstrate solar and lunar eclipses using a "disc of eclipses". Al-Adami was named in the Fihrist, written by the 10th century scholar Ibn al‐Nadīm.[1]

The astronomer Ibn al-Adami, who is thought by scholars to have been al-Adami's son, wrote Naẓm al‐ʿiqd (now lost), a zīj that used information obtained from the Sindhind, an Indian source translated into Arabic by the 8th century mathematician and astronomer Ibrāhīm al-Fazārī. The Naẓm al‐ʿiqd was first published in 949/950.[1]
