Ibn-i Lubudi (born 1210โ1267/68, Aleppo), full name Yahya bin Shamsuddin Muhammad bin Abdan bin Abdulvahid al-Lรผbรปdรฎ, was an Islamic scholar who wrote works in the fields of medicine, mathematics and astronomy.
After completing his education at the well-known al-Dakhwar medical school in Damascus, he entered the service of Mansur Ibrahim in Hims, Egypt (1239-1245). Later, upon the suggestion of Necmeddin Eyyup, he was appointed as a state inspector in Alexandria; After leaving Egypt, he lived in Syria.
Lubudi wrote several books on medical subjects; these include a study on Rheumatism, comments on the words of Hippocrates, and answers to the questions of Hunayn Ibn Ishaq. His two extant works include a discussion of fifty psychological-medical questions and an extensive commentary on Avicenna's "Law". The first of these works is kept in the El-Escurial library in Madrid and contains many interesting discussions, such as questions focusing on blood instead of the four moods of the body, objection to Galen regarding women's sperm production, the relationship of the movement of the arteries to the heart rhythm, and the view that the heart is the first limb instead of the brain.
In mathematics, he contributed with a summary of Euclid's teachings, "Arithmetic Textbook" and "A Treatise on Algebra". In the field of astronomy, he compiled astronomical tables called "El-Zahir", inspired by the paintings of the 9th century Abyssinian al-Hasib, and "El-Muqarab", based on his own observations; In 1325, Ibn Sarraj exhibited these paintings in Aleppo.
He also designed a universal astrolabe and developed new markings for the almucantar-quadrant and alternative trigonometric grids to the sine-quadrant.
One of his last works is "Tedkรฎkรผ'l-Mebรขhisi't-Tayyibe fรฎ Tahkรฎki'l-Mesรขili'l-Hilรขfiyye"; Here he studied various scientific issues in depth.
