Persian gardens may date back to as early as 4000 BC, but the tradition of a walled garden clearly began with the Achaemenid dynasty around the 6th century BCE, when the notion of an ‘earthly paradise’ spread through Persian literature. Persian gardens are closed gardens, not to be seen by outsiders – a true inner sanctum. The stylised trees of the orchard line up horizontally at the foot of this Gabbeh and are planted in the richest of soils… beyond is the meadow dotted with floral bushes and exotic birds… This is paradīsus, as rendered into Latin from the Avestan word pairidaēza-, albeit the contemporary Glitch version.
