Herzfeld no relation Achaemenid dynasty
Herzfeld believed that the reasons behind the construction of Persepolis were the need for a majestic atmosphere, a symbol for the empire, and to celebrate special events, especially the Nowruz. For historical reasons, Persepolis was built where the Achaemenid dynasty was founded, although it was not the center of the empire at that time.
Excavations of plaque fragments hint at a scene with a contest between Herakles and Apollo, dubbed A Greek painting at Persepolis.Architecture
Persepolitan architecture is noted for its use of the Persian column, which was probably based on earlier wooden columns. Architects resorted to stone only when the largest cedars of Lebanon or teak trees of India did not fulfill the required sizes. Column bases and capitals were made of stone, even on wooden shafts, but the existence of wooden capitals is probable.
In 518 BC, a large number of the most experienced engineers, architects, and artists from the four corners of the universe were summoned to engage and with participation, build the first building to be a symbol of universal unity and peace and equality for thousands of years.
The buildings at Persepolis include three general groupings: military quarters, the treasury, and the reception halls and occasional houses for the King. Noted structures include the Great Stairway, the Gate of All Nations, the Apadana, the Hall of a Hundred Columns, the Tripylon Hall and the Tachara, the Hadish Palace, the Palace of Artaxerxes III, the Imperial Treasury, the Royal Stables, and the Chariot House.
