Abstract: TheRasa 'il Ikhwan al-Safa' (Epistles of the Brethren of Purity) is a unique work in Islamic history consisting of approximately fifty-two epistles (rasa'il) on a wide range of subjects. The authors of this encyclopaedic compendium, who are believed to have lived in Basra in Iraq in the course of the 10th century, are said to have some connections with the Ismaili movement. This article compares and comments on two systems of scientific classification put forward by the Ikhwan: the first of a hierarchical nature and the second as set out by the coterie of scholars in 'Epistle VII'.
