The
Yaz culture was an early
Iron Age culture of
Bactria and
Margiana (ca. 1500-1100 BC). It has been regarded as a likely archaeological reflection of early
East Iranian culture as described in the
Avesta. So far, no burials related to the culture have been found, and this was taken as evidence of the
Zoroastrian practice of exposure or so-called
sky burial.
