Scientists have recalibrated one of ancient Egypt’s most important timelines, revealing new dates for Pharaoh Nebpehtire Ahmose’s reign — and shaking long-standing theories about a massive volcanic eruption that reshaped the ancient world.
The findings offer rare clarity on events stretching from the Nile Valley to the Aegean Sea.
A Scientific Push to Rethink Ancient History
Two researchers, Hendrik J. Bruins and Johannes van der Plicht, published the study in PLOS One, presenting radiocarbon evidence that challenges decades of scholarly consensus.
Their work centers on Ahmose, the founder of Egypt’s 18th Dynasty.
Ahmose is commonly credited with unifying Egypt after driving out the Hyksos.
His rule marked the start of the New Kingdom, a period historians often describe as Egypt’s political and cultural revival.
The study also ties into the Thera-Santorini eruption — a cataclysm so powerful that it scattered pumice across the Mediterranean.

The eruption inspired parts of the Atlantis legend and has been linked to the Book of Exodus.
But Bruins and van der Plicht argue that a major chronological misalignment has persisted for decades.
Their radiocarbon findings push the eruption further back in time.
The Mud Brick That Anchored a Pharaoh in Time
The research’s most compelling evidence came from a humble item: a mud brick.
It was excavated around 1900 from the Temple of Ahmose in Abydos.
Stamped on it is the throne name “Nebpehtire,” which identifies the king unambiguously.
Inside the brick, the researchers found a piece of straw — just enough organic material to radiocarbon date.
That tiny fragment revealed a construction period between 1517 and 1502 BCE.

This places the temple’s construction after Ahmose defeated the Hyksos and consolidated his rule.
The temple’s reliefs depict scenes of those battles, confirming that the brick reflects a post-conflict phase.
This makes it one of the first physical objects that can be confidently and scientifically tied to Ahmose’s lifetime.
Bruins noted that Ahmose was a common name, but the throne name locked in the association.
It was, in his words, “the first time we could put our hands on an object confidently related to this particular pharaoh.”
Figurines That Strengthened the Case
The team also analyzed six wooden shabtis — figurines intended to assist the deceased in the afterlife.
One shabti carried the name of a mayor of Thebes whose era overlapped with the reigns of Ahmose and his successor, Amenhotep I.
The radiocarbon reading from this figurine echoed the date range of the mud brick.
A one-sentence break.
This reinforced confidence in the new timeline.
Shabtis tend to travel far from their original burial places due to excavation and museum acquisition practices.
Yet this particular object preserved an organic signature strong enough for dating.
The linked dates between figurine and brick allowed the researchers to create one of the most stable chronological anchors for early 18th Dynasty history.
Revising the Thera-Santorini Eruption Timeline
For decades, many historians believed the massive eruption of Thera occurred around 1500 BCE.
Pumice from the eruption has appeared in archaeological sites in Israel and Egypt.
The disaster has been proposed as a parallel to the severe storms described on the Tempest Stela dating to Ahmose’s reign.
But the new radiocarbon comparisons suggest the volcano erupted 60 to 90 years earlier.
One short sentence.
That means the Tempest Stela likely describes an entirely different environmental event.
This conclusion removes the direct link between Ahmose’s reign and the eruption.
It also impacts theories connecting the eruption to early chapters of the Exodus narrative.
By placing Ahmose in the second half of the 16th century BCE — later than previously assumed — the study rewrites a section of the Mediterranean timeline that scholars have debated for generations.
Why This Redating Matters for Egyptian and Mediterranean Chronology
Ahmose’s rise to power sits at a pivotal crossroads.
His victory over the Hyksos transformed Egypt from fragmented rule into a unified empire.
This transition laid the foundation for the power centers of later pharaohs, including Hatshepsut, Thutmose III, and Tutankhamun.
A short standalone sentence.
Getting Ahmose’s dates right helps date everyone who came after.
The revision also sharpens the picture of regional change in the Aegean and Levant.
Earlier eruption dates push the environmental shockwave deeper into the Bronze Age, influencing interpretations of trade disruptions, settlement collapses, and cultural shifts.
Some scholars have long argued that Egyptian timelines were out of sync with Aegean data.
This study offers a scientific bridge between those historical sequences.
To summarize the differences, a small table helps clarify the shift:
| Item / Event | Previous Date | New Estimate |
|---|---|---|
| Thera-Santorini eruption | ~1500 BCE | ~1560–1590 BCE |
| Ahmose Temple Brick | Undetermined | 1517–1502 BCE |
| Ahmose’s Ascension | Often ~1550 BCE | Second half of 16th century BCE |
One sentence on its own.
It’s a shift that could reshape decades of archaeological work.
New Tools, New Timelines, and What Comes Next
The broader impact of this research lies in its method.
Radiocarbon dating isn’t new, but its use in cross-referencing volcanic debris with Egyptian temple artifacts marks a fresh level of precision.
The study also proves that museum objects — sometimes overlooked — can still yield major historical discoveries.
As more artifacts are sampled, researchers may revise other pharaonic timelines that have remained based on textual assumptions rather than scientific measurements.
One brief sentence here.
Chronology is the skeleton of history.
Misdated rulers affect how scholars interpret wars, migrations, cultural exchange, and literary traditions.
The Ahmose study might encourage similar radiocarbon collaborations across museums, burial sites, and volcanic archives around the Mediterranean.
Such projects could refine timelines that frame the entire Late Bronze Age — a period marked by shifting empires and sweeping environmental events.
Bruins and van der Plicht’s research may therefore ripple far beyond one pharaoh’s biography.
It signals that ancient history still has room to shift, sometimes dramatically, with a single scrap of organic material.
