Sacrificial fire

Worship or deification of fire (also pyrodulia, pyrolatry or pyrolatria) is known from various religions. Fire has been an important part of human culture since the Lower Paleolithic. The earliest known traces of controlled fire were found at Gesher Benot Ya‘aqov, Israel and dated to an age of 790,000 years, and religious or animist notions connected to fire must be assumed to reach back to such early pre-Homo sapiens times.

In Indo-European languages, there were two concepts regarding fire: that of an animate type called *egni- (cf. Sanskrit agni English ignite from Latin ignis, and Russian ogon), and an inanimate type *paewr- (cf. English - fire, Greek pyr, Sanskrit pu). A similar distinction existed for water.

Archaeologically, the earliest evidence for Indo-Iranian fire worship is found at the transition from the Sintashta-Petrovka to the Fedorovo culture around 1500 BC, together with first evidence of cremation. While cremation became ubiquitous in Hinduism, it came to be disavowed in Zoroastrianism. However, even earlier evidences of vedic fire altars have been found at the Indus Valley sites of Kalibangan and Lothal, giving rise to speculations towards earlier assumed the geographical location of the early Indo-Iranians.

Although the term "fire-worshippers" is primarily associated with Zoroastrians, the idea that Zoroastrians worship fire is originally from anti-Zoroastrian polemic. Instead, fire—even in a Fire temple (the Zoroastrian terms are more prosaic and simply mean "house of fire")—is considered to be an agent of purity and as a symbol of righteousness and truth. In the present day this is explained to be because fire burns ever-upwards and cannot itself be polluted. Nonetheless, Sadeh and Chaharshanbe Suri are both fire-related festivals celebrated throughout Greater Iran and date back to when Zoroastrianism was still the predominant religion of the region.
