Origin of the word paradise
The term paradise derives from old Persian pairi [around] daeza [wall brick or shape]. Composed in one word it means walled- in garden or compound. It was introduced in European languages through Greek when Xenophon translated it to paradeisos. The Persian tradition of building enclosed gardens with rectangular water basin and odorous plants stems from the royal Achmenide tradition of the enclosed hunting grounds of lions which was a ritual practice enforcing their divine –royal authority. Later the paradisian garden tradition was expanded to Moghul India (Taj Mahal) and under Islam in the Middle Eastern until Andalusia (Alhambra ,Granada) and later to Europe. The Hebrew word pardes, derives from Greek or Persian and means garden, grove or orchard.

Persian gardens are multi-functional: they not only serve contemplation and relaxation, but are also a representation and manifestation of power. Designing and implementing a garden demonstrates the occupation of land, holding audiences and celebrating victories or marriages in these gardens signal superiority, or social and political bonds.

The paradise garden is a form of garden of Old Iranian origin, specifically Achaemenid which is formal, symmetrical and most often, enclosed. The most traditional form is a rectangular garden split into four quarters with a pond in the center, a four-fold design called chahar bagh (“four gardens”).[1] One of the most important elements of paradise gardens is water with ponds, canals, rills, and fountains all being common features. Scent is an essential element with fruit-bearing trees and flowers selected for their fragrance.
