The community of Shiite alchemists gathered under the pen name of Ǧābir b. Ḥayyān produced an important corpus first studied by Paul Kraus, who dated it between the third/ninth and fourth/tenth centuries. The religious, doctrinal and political issues of the corpus – especially in the last two collections – show that the Ǧābireans were a real sectarian trend unknown to heresiographers. Kraus, along with some scholars after him, understood the Ǧābirean community to be an expression of Ismaili thought. This paper aims to reconsider: a) the religious and political affiliation of Ǧābir's alchemical community in the light of textual comparisons that show a close connection between the Ǧābireans and the esoteric tenets characterizing the Shiite ġuluww as mirrored in the heresiographic sources of the late third/ninth and early fourth/tenth centuries, and in the Ġulāt literary sources; and b) the last collection of the Ǧābirean corpus as a polemical outcome specific to the Shiite milieu between the lesser and the greater Occultation of the twelfth Imam.
