Asman (Avestan: 𐬀𐬯𐬨𐬀𐬥, romanized: asman) is the Avestan and Middle Persian name of the Zoroastrian divinity that is the hypostasis of the sky.
Nomenclature[]
The Word Asman comes from the Proto-Indo-Iranian *Háćmā, from which comes the Indo-European *h₂eḱ- that mean stone, so Asman is the stone that holds up the firmament. Asman is cognate with other similar words like the Germanic himins (Gothic), Heaven (English), himel (Old Frisian) between among other words.
Zoroastrianism[]
Originally the word for heaven was dyaoš during in the Indo-Iranic/Early Achaemenid times, in where Asman has not yet appeared.
But in the Zoroaster´s reform dyaoš becomes into the word diiaoš being a another name for the hell, this was due to Dyēus´s demonization by Zoroaster. Thus Asman becomes into the new for Heaven in the Greater Iran until the morden Iran.
Iran[]
In the morden Iran exist a town named Dom-e Asman, may be by the zoroastrian angel.
