This book by Antonio Panaino discusses the development of the Iranian cosmographical world and its interaction with the Greek, Mesopotamian and Indic civilizations. By undertaking such a study, the author places the Iranian intellectual tradition in perspective vis-à-vis other ancient civilizations and demonstrates the depth and importance of the Mazdean tradition, which was able to absorb and systematize foreign knowledge. Panaino shows the presence of both Aristotelian and Neo-Platonist traditions in the Iranian intellectual scene, though somewhat changed and acculturated to the Mazdean ideas and world-view. Hence, the book is a lively and interesting study of the juxtapositioning of various scientific and philosophical ideas at play in the Mediterranean, Iranian and Indic worlds. This volume was previously published by the Jordan Center for Persian Studies, University of California – Irvine.
