Building a city like Rome
In Istanbul buildings, palaces, fora, the hippodrome, temples and water cisterns are built just like in Rome. Rome was built on 7 hills and the river the Tiber. In Istanbul there was no river as large as the Tiber but a creek. This Lycos creek is now called Bayrampasa Deresi. This creek was enough and one built a copy of Rome in Istanbul.
With seven candles
Emperor Constantine believed in the luck of the number seven. The head room of the palace was called “Hepta Lichnos” which means “with seven candles”. There was a parade to protect the Emperor which contained 7 continents. The Emperor was painted in paintings as a sun in the middle of 7 stars which turned around him. An example is the statue Apollo Sol Invicto in Cemberlitas. There are two Constantinopels, a Roman and a Byzantine. These cities were eqaul cities. The Roman Empire has endured like this for 65 years led by 7 different emperors.
