Chahar-Bagh or Charbagh?

Most of the researchers noted that CHARBAGH is the most important pattern of Persian garden and it is an "Archetype". In other side we have CHAHARBAGH which is formed by two perpendicular axes in garden and divide it into four square shape parts. This paper aims to challenge "Chahar-Bagh" Or "Charbagh" ,which is correct? So, that is the main question. In order to find the answer, with a deductive approach, the paper tries to recognize all the documents about "Chahar-Bagh" and "Charbagh", among historical documents such as, the first documents of PASARGAD garden, available historic books: IRSHAD-OL-ZERA-E, ROZAT-OL-SEFAT, BABURNAMEH and we search it in Achaemenian inscription, and also in Persian miniature and Persian garden-carpet. In most of the historic books we can find, description of un-axial pattern for creating Persian garden. We could not find any words which means CHAHAR (Four) in available Achaemenian inscriptions. In Persian Garden –carpets and Persian miniature we can observe both patterns of CHAHAR-BAGH archetype which includes: two perpendicular axes pattern and uni-axial pattern as we see the same in Persian Miniatures. In conclusion we can form a hypothesis which tells us, shaping four square shape parts or CHAHAR-BAGH garden is related to the Safavid period. Iranian built un-axial garden before that period and call it CHARBAGH.
