'agdistis' originates from Phrygian mythology, specifically the deity 'Agdistis', where 'ag-' meant 'both' and 'distis' referred to 'sexes'.

'Agdistis' was a deity in Phrygian mythology and retained its name and characteristics as it was adopted into Greek mythology.

Initially, it referred to a deity with dual characteristics, and this meaning has largely remained the same in modern references to mythology.
