"Mantegh-O-Tair, undoubtedly, is the most flourishing mystical poem in Persian literature in the form of 'Masnavi'. In this work, the journeys of God-seeking mystics, from request to mortality (Fana), is depicted through the journey of sphinx-seeking birds in a symbolic and coded language.Attar, prior to the start of the narration in an artistic introduction, introduces thirteen bires (mystics): Hoopoe, Mosiche, Parrot, Partridge, Tong-baz or Tond-baz, Francolin, Nightingale, Peacock, Tazarv, Ringdove, Turtledove, Hawk, Golden bird. The writer's viewpoints are about this symbolic introduction. The writer, in the first point of view entitled "Atar's lost bird", identifies the fifth birds as 'dove', rather than 'Tong-baz'. In the second view named "Hoopoe and twelve birds", the writer is concerned with counting the birds as 'twelve plus one' rather than 'thirteen'. The last view called "Golden-bird" deals with decoding this extraordinary and strange bird.
