The Preservation Lottery
When Egyptian authorities unveiled their findings from Abu Qir Bay this month, the images stunned observers worldwide: a massive quartz sphinx bearing the cartouches of Pharaoh Ramesses II, a white marble statue of a Roman nobleman, limestone buildings that once served as temples and homes, according to the Egyptian Ministry of Tourism and Antiquities. Here was Canopus, the ancient pilgrimage city where countless people once traveled to seek healing at the sanctuaries of Osiris and Serapis, rising from beneath the Mediterranean after more than a millennium underwater. The stone survivors created an illusion of completeness, as if archaeologists were recovering a lost world intact.
But this spectacular haul reveals less about what ancient Canopus was and more about what the sea chose to preserve. The physics of underwater decay, not historical importance, determines which fragments of vanished civilizations survive to tell their stories. What we're excavating isn't the past. It's what's left after chemistry has had its way.
What the Sea Takes
Metal objects do not fare well underwater, but stone is more durable, according to marine conservation principles documented by the Supreme Council of Antiquities. This simple fact of material science has systematically erased entire categories of ancient life from the archaeological record. The bronze coins that fueled Canopus's economy when it served as one of the most important ports for Egypt before Alexandria's foundation in the 4th century BC, per the Ministry of Tourism and Antiquities, have corroded into nothing. The iron tools that built the city's temples, the metal fittings that held ships together, the copper vessels that stored wine and oil in merchant quarters have all dissolved into the Mediterranean.
Meanwhile, the 125-meter dock discovered at the site survives because organic materials such as wood can last surprisingly well due to the lack of oxygen in waterlogged places, according to underwater preservation research cited by the Supreme Council of Antiquities. The stone anchors and harbour crane dating back to the Ptolemaic and Roman eras remain because they were carved from rock, not cast from metal. The reservoirs and rock-carved ponds for domestic water storage and fish cultivation endure because limestone doesn't corrode.
This creates a profoundly distorted picture of ancient Canopus. The city was a prominent center during the Ptolemaic dynasty, which ruled Egypt for nearly 300 years, and remained significant during the Roman empire's 600-year governance, per historical records compiled by the Egyptian Ministry of Tourism and Antiquities. It sat on the western side of the Nile Delta, at the mouth of the westernmost branch of the Nile, positioned opposite its twin city Thonis-Heracleion on the other bank. Canopus was a living, working port where ships loaded grain and unloaded goods, where merchants haggled over prices, where pilgrims bought offerings for the gods, where families cooked meals and children played in streets.
Almost none of that daily life survives. The wooden furniture, the textile awnings that shaded market stalls, the leather sandals, the papyrus documents recording transactions and prayers, the food remains, the everyday pottery that broke and was discarded, all the perishable evidence of how people actually lived has vanished. What remains are the monuments: temples, statues, the infrastructure of power and worship rendered in stone.
The Bureaucracy of Memory
Even among the objects that survive the sea's chemistry, human systems add another filter. Only specific material is allowed to be retrieved from the underwater city according to strict criteria, per regulations enforced by the Supreme Council of Antiquities through Secretary-General Mohamed Ismail Khaled. The underwater operation that produced these recent finds is the first such operation to take place in Egypt in 25 years, according to the Ministry of Tourism and Antiquities, a gap that raises questions about which heritage gets excavated before it's lost forever.
French archaeologist Franck Goddio and his team, working under the auspices of the European Institute for Underwater Archaeology in collaboration with the Egyptian Ministry of Tourism and Antiquities, have been exploring these waters since the 1990s. Many initial finds were made during the team's work in the 1990s through 2010s, and the British Museum showcased some 200 artifacts in their Sunken Cities: Egypt's Lost Worlds exhibition in 2016. Three decades of excavation have produced a consistent pattern: monumental stone sculptures, architectural elements, religious objects, the durable remnants of official culture.
The pattern isn't random. It reflects both what survives and what excavators are permitted to retrieve. A beheaded Ptolemaic figure made of granite, the lower half of a Roman nobleman's likeness carved from marble, limestone buildings that may have served as places of worship, residential spaces and commercial or industrial structures, all recovered according to criteria that privilege the monumental over the mundane, the official over the ordinary.
Sinking While We Watch
The preservation lottery continues in real time. Alexandria is sinking by more than 3mm every year, according to geological surveys cited by Egypt's tourism and antiquities minister Sherif Fathi. The modern Egyptian coastal town of Abu Qir sits atop a large proportion of Canopus's western suburbs, while the eastern suburbs lie underwater in Abu Qir Bay. The city is disappearing twice: once into the sea after earthquakes and rising sea levels submerged it by the 8th century AD, and again as modern Alexandria subsides beneath the Mediterranean.
What will survive from our era when future archaeologists excavate 21st-century Alexandria? The concrete harbor walls, certainly. The ceramic pipes and stone foundations, probably. The metal reinforcement bars in buildings will corrode away. The plastic that chokes our oceans might persist, a toxic time capsule. But our actual lives, the digital records we've entrusted to magnetic storage and cloud servers, the photographs and documents and communications that define our existence, will vanish as completely as the papyrus scrolls of ancient Canopus.
The recent discoveries of remnants of an ancient harbor and a merchant ship, per the Ministry of Tourism and Antiquities, offer a glimpse of commercial life that the stone temples cannot provide. But these are fragments, survivors of a preservation lottery where durability trumps significance. Canopus was first mentioned in writing in the 6th century BC, in a poem by Solon, yet the foundation date remains unknown because the site had been settled for centuries before the Greeks, and those earlier layers have been erased by time and tide.
The quartz sphinx of Ramesses II recovered from Abu Qir Bay will join museum collections, another spectacular monument to add to our understanding of pharaonic Egypt. But it tells us nothing about the pilgrims who traveled to Canopus seeking divine intervention, nothing about the priests who served in the sanctuaries, nothing about the merchants and sailors and families who made the city live. Those stories are written in materials the sea consumed: wood and metal and fiber and flesh, all returned to the elements that formed them.
We call these underwater excavations the recovery of lost worlds. More accurately, they're the recovery of what the chemistry of decay chose to spare. The past we excavate is not the past that existed. It's the past that endured, selected not by importance but by the arbitrary physics of preservation. The rest is silence, settling into Mediterranean sediment, sinking 3mm deeper every year.
