Persepolis
Darius I built the greatest palace at Persepolis on the western side of platform. This palace was called the "Apadana". The King of Kings used it for official audiences. The work began in 518 BC, and his son, Xerxes I, completed it 30 years later. The palace had a grand hall in the shape of a square, each side long with seventy-two columns, thirteen of which still stand on the enormous platform. Each column is high with a square Taurus (bull) and plinth. The columns carried the weight of the vast and heavy ceiling. The tops of the columns were made from animal sculptures such as two-headed lions, eagles, human beings and cows (cows were symbols of fertility and abundance in ancient Iran). The columns were joined to each other with the help of oak and cedar beams, which were brought from Lebanon. The walls were covered with a layer of mud and stucco to a depth of 5 cm, which was used for bonding, and then covered with the greenish stucco which is found throughout the palaces.
Megalopolis, Greece
The city was founded through a synodical of twenty to forty neighbouring communities between 371 and 368 BC by the Arcadian League in an attempt to form a political counterweight to Sparta. Megalopolis was a member of the Arcadian League after its foundation until the dissolution of the federation in 362 BC. In 331 BC, Megalopolis was invaded by the Spartans and there was a battle with the Macedonians that came to Megalopolis' help. In the 270s BC, Aristodamos the Good, managed to take control over the city as a tyrant backed by Macedon. In 235 BC, the second tyrant of the city, Lydiades, gave up control over the polis and the city became a member of the Achaean League. In 222 BC, the Spartan king Cleomenes III burnt down the city but it was rebuilt in the years after the destruction. As a member of the Achaean League, Megalopolis had a profound influence on the federal politics and it was the hometown of several notable Achaean statesmen and figures such as Philopoemen, Lykortas and Polybius himself. The city remained populated under the Romans but by the 6th century it was almost completely abandoned. The nearby village of "Sinano" (Σινάνο), situated south of the ancient city, was renamed Megalopoli after Greek Independence.
