ABU’L-ḤASAN HERAVĪ

 

ABU’L-ḤASAN ŠAMSĪ HERAVĪ, medieval mathematician; Seǰzī (late 4th/10th century) quotes some of his propositions regarding the trisection of an angle; and these are all that survive of his work (F. Woepcke, L’algèbre d’Omar Alkhayyāmī, Paris, 1851, pp. 118-19, 122). It was suggested (Suter, Mathematiker, p. 228) that he may be the ʿAbdallāh b. Moḥammad Heravī who wrote a Resāla fī anna ketāb Oqlīdes fi’l-oṣūl mabnī ʿala’l-taʾlīf al-manṭeqī fī moqaddemātehe (“Epistle on the fact that Euclid’s book The Elements rests upon logical composition in its premises”). The suggestion may be valid if the latter author is not the mystic ʿAbdallāh Anṣārī (fl. second half of the 5th/11th cent.).
