The Death in Babylon & Ptolemy’s Daring Corpse Hijack (323 BC)

When Alexander the Great died in the palace of Nebuchadnezzar II at Babylon in June 323 BC at age thirty-two, his body was embalmed in honey and placed in an elaborate golden anthropoid sarcophagus [1,3]. Over two years, imperial craftsmen constructed a magnificent funerary carriage adorned with Ionic colonnades and golden bells, intended to convey the king’s corpse back to the royal Macedonian necropolis at Aegae (Vergina) [1,3].

In 321 BC, as the cortege reached Syria, General Ptolemy I Soter executed one of the boldest geopolitical kidnappings in antiquity [1,3,5]. Ptolemy intercepted the carriage, diverted the king’s corpse to Egypt, and temporarily entombed Alexander at Memphis according to ancient Egyptian pharaonic rites, cementing Ptolemaic legitimacy over the Nile kingdom [1,3,5].

"In 321 BC, Ptolemy hijacked Alexander’s golden funerary cortege in Syria, diverting the conqueror’s body to Egypt to legitimize his royal dynasty."

The Soma Mausoleum & The Glass Sarcophagus of Alexandria

Under Ptolemy II Philadelphus and Ptolemy IV Philopator (c. 215 BC), Alexander’s remains were transferred to his namesake capital, Alexandria, and placed inside a monumental royal mausoleum known as the *Soma* or *Sema* ("The Body") located in the palatial Brouchion district at the intersection of the Canopic and Soma avenues [2,3,4].

Originally interred in solid beaten gold, the sarcophagus was melted down in 89 BC by Ptolemy X Alexander I to pay mutinous mercenary legions during a civil war [1,3]. The golden casket was replaced by a translucent alabaster and glass sarcophagus, allowing visiting dignitaries to view the mummified king through crystalline glass [1,2,3].

Imperial Roman Pilgrimages: Julius Caesar, Augustus, and Caracalla

During the Roman era, visiting Alexander’s tomb was the ultimate pilgrimage for military commanders and emperors [2,4,6]:

- **Julius Caesar (48 BC)**: Visited the Soma during the Alexandrian War, paying solemn homage and weeping at the realization that Alexander had conquered the known world by age thirty-two [2,4].

- **Octavian / Augustus (30 BC)**: Following his victory over Mark Antony and Cleopatra, Augustus placed a golden crown and flowers upon the mummy. Ancient biographer Suetonius recorded that when Augustus touched Alexander’s face, he accidentally broke a piece off the mummified nose [4,6].

- **Septimius Severus & Caracalla (AD 199–215)**: Severus visited the tomb and, alarmed by tomb robbers, ordered the burial vault sealed with mystical books and occult papyri [2,4]. In AD 215, Emperor Caracalla entered the crypt, took Alexander’s purple mantle, belt, and signet ring, and placed them upon his own person [4,6].

"Roman biographer Suetonius recorded that Emperor Augustus accidentally broke a piece off Alexander’s mummified nose while placing a golden crown on the corpse."

The AD 365 Alexandria Tsunami & The 4th-Century Silence

Historical records of the tomb abruptly cease in the late 4th century AD. In AD 365, a catastrophic magnitude-8.0 earthquake off Crete triggered a massive tsunami that inundated Alexandria’s coastal palace quarters, submerging portions of the ancient royal district [1,2,7].

Furthermore, in AD 391, Christian Emperor Theodosius I outlawed pagan worship and ordered the destruction of non-Christian sanctuaries across the empire [1,2]. In a famous homily delivered around AD 400, John Chrysostom, Patriarch of Constantinople, taunted pagan listeners by asking: "Where is the tomb of Alexander? Show it to me, and tell me the day on which he died!"—proving the exact location of the monument had been forgotten by late antiquity [1,2,7].

Modern Archaeological Quests: From Kom el-Dikka to Siwa Oasis

Over the past two centuries, more than 140 formal archaeological expeditions have searched for Alexander’s tomb [1,5,7]. Theories center on four primary hypotheses:

1. **Kom el-Dikka (Central Alexandria)**: The Polish Centre of Mediterranean Archaeology excavated an extensive Roman theater, university auditoriums, and bathhouses near the ancient crossroads where the Sema stood [1,7].

2. **Nabi Daniel Mosque**: Local Alexandrian tradition holds that Alexander lies in a sealed crypt beneath the historic Nabi Daniel Mosque, though excavations by Heinrich Schliemann and the Egyptian Antiquities Service yielded only medieval Islamic burials [1,5].

3. **The St. Mark Body Swap Hypothesis**: Historian Andrew Chugg proposed that 9th-century Venetian merchants who stole St. Mark’s mummified body from Alexandria in 828 actually smuggled Alexander’s remains into St. Mark’s Basilica in Venice [1,7].

4. **Siwa Oasis**: Ongoing desert surveys explore whether Ptolemy respected Alexander’s alleged dying wish to be buried near the Oracle of Ammon at Siwa [1,5].

Frequently Asked Inquiries

Was Alexander the Great originally buried in Alexandria?

No. Alexander died in Babylon in 323 BC. His body was embalmed in honey, hijacked in Syria by Ptolemy I, and initially entombed at Memphis before Ptolemy IV moved his remains to the grand Sema mausoleum in Alexandria around 215 BC.

Which Roman emperors visited Alexander’s tomb?

Julius Caesar (48 BC), Octavian Augustus (30 BC), Roman Emperor Septimius Severus (AD 199), and Emperor Caracalla (AD 215) all visited and documented viewing Alexander’s body in his crystal sarcophagus.

Why did the tomb disappear in the 4th century AD?

The location was lost due to a combination of the catastrophic AD 365 tsunami that flooded Alexandria’s coastal palace district, the destruction of non-Christian shrines under Emperor Theodosius I in AD 391, and centuries of subsequent urban rebuilding.
