[4] It is uncertain when the name Sandaramet entered Armenian; it may have taken place under the Achaemenid Empire (550–330 BC).
The 5th-century Armenian author Agathangelos uses the word sandarametakan nnĵecealkc ("those asleep in the underworld") to refer to the dead.
[6] The usage of word to refer to the underworld indicates that its introduction to Armenian took place during a period when earth was seen as the home of the dead.
[9] In the account of Agathangelos, the Arsacid Armenian king Tiridates III (r. 298–330 AD) mentions the "šahapet of the tombs", which most likely refers to Spandaramet.
The Armenian word šahapet (derived from Old Persian xšaθrapati) was used to refer to supernatural beings.
