Obelisk of Theodosius

The Obelisk of Theodosius is the Ancient Egyptian obelisk of Pharaoh Thutmose III re-erected in the Hippodrome of Constantinople by the Roman emperor Theodosius I in the 4th century AD. The obelisk was erected during the 18th dynasty by Pharaoh Thutmose 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 Obelisk of Theodosius is of red granite from Aswan and was originally 30m tall, like the Lateran Obelisk. The lower part was damaged in antiquity, probably during its transport or re-erection, and so the obelisk is today only 18 meters.
