<div>Abu Ya'qub al-Sijistani was a prolific author of many seminal Islamic texts, and is known as the "intellectual missionary" of Fatimid Ismailism. He wrestled with a variety of key theological and philosophical issues during his career, and succeeded in outlining an alternative vision of Islam which has a surprisingly modern appeal. His important work <i>Kashf al-Mahjub</i> (literally "the unveiling of the hidden") is published here under the rubric <i>Creation and Resurrection</i>. Although the original Arabic text appears to have been lost, a near-contemporaneous Persian translation has survived and was edited for the first time by the late Henry Corbin. This new edition of the Persian text, published alongside the first complete English translation and introduction, enables this fascinating work to be read and appreciated anew by a fresh generation of scholars and readers interested in the history of early Islamic philosophy and theology.<br></div>
