Famous for the discovery of the principle that a body immersed in fluid loses in weight by an amount equal to the weight of the fluid displaced. Many of his works were well known to Muslim Philosophers through their Arabic translation and commentaries on them by Hunain ibn Ishaq (d. 246/877), al-Mahani (d. c.261-71 /874-84) and Yusuf al-Khuri (fl. 290-6/902-8).
