Obelisk of Theodosius is an obelisk and pillar in Türkiye, Asia. UNESCO World Heritage List: Historic Areas of Istanbul gives its chronology as “Carved c. 1450 BCE; re-erected 390 CE.” Its listed material is Granite. Its height is listed as 19.6 m (estimated). UNESCO World Heritage List: Historic Areas of Istanbul also records: “Temple obelisk.”
The upper part of a Karnak obelisk, re-erected in Constantinople's Hippodrome.
What makes it extraordinary
Pedestal Bas-Reliefs and Imperial Imagery
The obelisk rests on a marble pedestal decorated with bas-reliefs dating to the time of its re-erection in Constantinople. These carvings depict Emperor Theodosius I and his court observing spectacles from the imperial box in the Hippodrome. Specific scenes include the emperor offering laurels of victory, a chariot race, and kneeling barbarians presenting tribute. The reliefs also feature cultural details such as musicians, dancers, and the water organ of Ctesibius, serving as a visual record of late Roman court life.
The Obelisk of Theodosius was originally commissioned by Pharaoh Thutmose III during the 18th dynasty, around 1450 BC. It was first erected to the south of the seventh pylon at the Great Temple of Karnak. The monument's four faces feature a single central column of hieroglyphic inscriptions that celebrate the Pharaoh's military victory over the Mitanni on the banks of the Euphrates River. Although it now stands in Istanbul, it remains a significant artifact of Egyptian imperial history.
In 357 AD, the Roman emperor Constantius II ordered the obelisk to be moved from Karnak to Alexandria to commemorate his ventennalia, marking twenty years on the throne. It was transported along the Nile River alongside another obelisk, which was eventually sent to Rome to become the Lateran Obelisk. While its counterpart was erected in the Circus Maximus that same year, this specific obelisk remained in Alexandria for over three decades before its final journey to Constantinople.
To facilitate the transportation and re-erection of the massive granite shaft, four bronze cubes were placed between the corners of the obelisk and its marble pedestal. These cubes served a critical structural role in distributing the weight of the monument. During later restorations, missing pieces at the pedestal's bottom corners were replaced with porphyry cubes of identical dimensions. These porphyry replacements rest directly on the original bronze cubes, maintaining the structural integrity and alignment of the ancient Egyptian monolith.
The obelisk exhibits a prominent vertical gash on its north face, which appears like a canal when viewed from above. This feature, along with energetic restorations of the pedestal, suggests the monument suffered a serious accident in antiquity, possibly an earthquake. The repairs to the base, including the replacement of corner pieces with porphyry, are linked to the cracking of the granite shaft itself. These physical markers provide evidence of the monument's long history of maintenance and survival against environmental hazards.
Originally standing approximately 30 meters tall—comparable to the Lateran Obelisk—the monument suffered significant damage to its lower section in antiquity. This damage likely occurred during its transport or re-erection process. Consequently, the granite shaft currently measures between 18.54 and 19.6 meters in height. When the marble pedestal is included, the total height of the structure reaches 25.6 meters. The missing lower portion accounts for the discrepancy between its original Egyptian scale and its current Roman configuration.
The east face of the pedestal features a Latin inscription composed of five hexameters. The text personifies the obelisk, stating it was 'conquered and vanquished' and raised to the sky in 'three times ten days' (30 days) under the supervision of the judge Proculus. This inscription emphasizes the submission of the monument to Theodosius and his descendants. Although slightly damaged at the bottom, the full text was preserved through transcriptions made by travelers during the 16th century.
On the west face of the pedestal, a Byzantine Greek inscription repeats the theme of the obelisk's erection but contains a chronological discrepancy compared to the Latin text. While the Latin version claims the work took 30 days, the Greek elegiac couplets state the process required 32 days. This inscription also credits Emperor Theodosius as the only one who dared to raise the 'four-sided column' that had long lain heavily on the ground, further highlighting the prestige of the engineering achievement.
Emperor Theodosius I had the obelisk transported from Alexandria to Constantinople in 390 AD, where it was placed on the spina of the Hippodrome. The monument survived the Byzantine era and the subsequent 17th-century demolition of the Hippodrome during the Ottoman Empire. Today, it stands in the Sultanahmet Meydanı, also known as At Meydanı. The re-erection was a significant engineering feat of the late 4th century, intended to project imperial power in the new capital.
The Greek inscription on the pedestal provides evidence of political shifts in the Theodosian court. In 392 AD, the official Proculus, who supervised the obelisk's erection, fell out of favor with the emperor. Consequently, his name was erased from the Greek text, a practice known as damnatio memoriae. However, the name was re-inscribed several years later. This physical alteration to the monument reflects the volatile nature of imperial politics and the subsequent rehabilitation of Proculus's historical legacy.
