Aeshma

Aeshma (Aēšma) is the Younger Avestan name of Zoroastrianism's demon of "wrath." As a hypostatic entity, Aeshma is variously interpreted as "wrath," "rage," and "fury." His standard epithet is "of the bloody mace." Tri-syllabic aeshma is already attested in Gathic Avestan as aeshema (aēšəma), though not yet - at that early stage - as an entity. The word has an Indo-Iranian root. In the Zoroastrian texts of the 9th-12th centuries, aeshma appears as Middle Persian eshm or kheshm, continuing in Pazend and New Persian as kashm. Judaism's Asmodai (Talmudic ˀšmdˀy, Book of Tobit asmodios) derives from Avestan aeshma.daeva.

[Persian] "Fury". One of the Daevas, Aesma Daeva ("madness") is the demon of lust and anger, wrath and revenge. His wrath is mainly directed towards the cow. He is the personification of violence, a lover of conflict and war. Together with the demon of death, Asto Vidatu, he chases the souls of the deceased when they rise to heaven. The Jewish evil spirit Asmodeus is derived from his image. His eternal opponent is Sraosa.
