Here then is the fruit of Elena Kuz'mina's life-long quest for the Indo-Iranians. Already its predecessor (Otkuda prishli indoarii?, published in 1994) was considered the most comprehensive analysis of the origins of the Indo-Iranians ever published, but in this new, significantly expanded edition (edited by J.P. Mallory) we find an encyclopaedic account of the Andronovo culture of Eurasia. Taking its evidence from archaeology, linguistics, ethnology, mythology, and physical anthropology pertaining to Indo-Iranian origins and expansions, it comprehensively covers the relationships of this culture with neighboring areas and cultures, and its role in the foundation of the Indo-Iranian peoples.
