Obelisk of Theodosius
The Obelisk of Theodosius (Turkish: Dikilitas) is the Ancient Egyptian obelisk of Pharaoh Tutmoses III re-erected in the Hippodrome of Constantinople by the Roman emperor Theodosius I in the 4th century AD.
History
The obelisk was first set up by Tutmoses III (1479–1425 BC) to the south of the seventh pylon of the great temple of Karnak. The Roman emperor Constantius II (337-361 AD) had it and another obelisk transported along the river Nile to Alexandria to commemorate his ventennalia or 20 years on the throne in 357. The other obelisk was erected on the spina of the Circus Maximus in Rome in the autumn of that year, and is today known as the Lateran obelisk, whilst the obelisk that would become the obelisk of Theodosius remained in Alexandria until 390, when Theodosius I (378-392 AD) had it transported to Constantinople and put up on the spina of the Hippodrome there.
