From Eden to Exodus: Synchronizing Ancient Timelines through the Fragments of Manetho
One particularly fascinating aspect of reading the reconstructed writings of Manetho is the way they draw upon various sources to attest that the Great Flood was recognized by numerous ancient cultures—including the Sumerians, Babylonians, Egyptians, and Greeks. Even more striking is that some of these historians actively debated specific dates, attempting to determine precise chronological frameworks for events such as the time span from Adam to Noah, and from Noah to the Exodus. The Great Flood is often dismissed in modern times as a purely religious myth or fabrication, yet it is one of those events that appears with remarkable consistency across a wide range of ancient traditions. This cross-cultural testimony suggests a shared memory of a cataclysmic event, preserved in the historical consciousness of civilizations that otherwise had little in common.
The early chronology of human history is often perceived through the prism of sacred texts, most notably the Hebrew Bible. Yet, beyond the canonized accounts lies a web of traditions, chronicles, and historical interpretations that attempt to harmonize—or challenge—biblical timelines. One of the most intriguing figures in this dialogue is Manetho, a third-century BCE Egyptian priest and historian, whose work survives only through the fragmented quotations of later writers. Despite the loss of his original texts, Manetho’s influence on biblical chronologists and his controversial interpretations, particularly concerning figures such as Moses and Joseph, make his contributions vital to any attempt to reconstruct a unified view of ancient time.
This essay examines the major chronological milestones of biblical history—from Adam to the Great Flood, from the Flood to Abraham, and through the age of Joseph and Moses—as seen through the lens of Manetho’s surviving fragments and their later interpreters: Josephus, Eusebius, Julius Africanus, and George Syncellus. Drawing from the Septuagint, Masoretic Text, Samaritan Pentateuch, and ancient Egyptian king lists, we aim to understand how ancient authors attempted to map sacred chronology onto historical frameworks, often producing widely divergent timelines.
1. Manetho: The Historian of the Pharaohs
Manetho of Sebennytos lived during the reign of Ptolemy I or II (3rd century BCE) and is credited with composing the Aegyptiaca, a history of Egypt written in Greek. His work sought to present a coherent dynastic chronology of the Egyptian kings, dividing them into thirty or more dynasties. Unfortunately, the original Aegyptiaca has not survived; we know it only through later citations, especially by:
-
Josephus (1st century CE), in Against Apion.
-
Eusebius of Caesarea (c. 260–339 CE), in his Chronicon.
-
Julius Africanus (c. 160–240 CE).
-
George Syncellus (8th century CE), who preserved extensive fragments from Africanus and Eusebius.
These authors often used Manetho to either support or dispute biblical chronology, giving us insight into how Egyptian and biblical timelines were reconciled or challenged.
2. From Adam to the Great Flood
The biblical genealogies in Genesis 5 trace ten generations from Adam to Noah. Depending on the textual tradition, the time from Adam to the Flood varies widely:
-
Masoretic Text (MT): ~1,656 years
-
Septuagint (LXX): ~2,242 years
-
Samaritan Pentateuch: ~1,307 years
Josephus, writing in the first century CE, favored the LXX chronology in Antiquities of the Jews (Book 1, Chapter 3). He explicitly cites the long lifespans of the antediluvian patriarchs, emphasizing the total of 2,242 years from Adam to the Flood (Ant. I.3.3).
Manetho himself does not offer a direct biblical chronology, but Eusebius and Syncellus, using Manetho’s dynastic lists, attempt to correlate the mythological pre-dynastic Egyptian reigns (of gods and demigods) with the time before the Flood. Eusebius refers to reigns of thousands of years under gods such as Ptah and Ra, which he synchronizes with biblical antediluvian times (Eusebius, Chronicon, Armenian version).
Manetho’s divine dynasties list reigns totaling over 24,000 years before Menes, which Syncellus and Africanus take as mythic or symbolic, potentially reflecting the vast ages of Genesis patriarchs.
3. From Adam to Noah
The period from Adam to the birth of Noah is nested within the Adam-to-Flood framework. Genesis 5 provides detailed age data for each patriarch at the birth of their sons. According to the MT, Noah was born 1,056 years after Adam, and the Flood occurred when Noah was 600 years old.
The LXX increases the ages at fatherhood for several patriarchs, resulting in a much longer timeline:
-
Noah is born around 1,464 years after Adam.
-
The Flood occurs 2,242 years after Adam (Josephus, Antiquities, I.3.3).
Syncellus and Africanus, working with both biblical and Egyptian sources, treat these early ages as literal but symbolic, suggesting they represented dynastic periods or astronomical cycles.
4. From the Flood to Abraham
Postdiluvian chronology, drawn from Genesis 11, presents another divergence:
-
MT: ~292 years from the Flood to Abraham
-
LXX: ~1,072 years
-
Samaritan Pentateuch: ~942 years
These differences arise from variances in the ages of patriarchs at the birth of their sons. The LXX inserts an additional 100 years in several genealogies, greatly expanding the timeline.
Eusebius and Africanus, who appear to follow the LXX tradition, list these extended intervals and use them to correlate the emergence of early Near Eastern civilizations with postdiluvian events.
Although Manetho does not mention Abraham directly, some scholars (e.g., Eduard Meyer, Geschichte des Altertums) have speculated that Manetho’s early dynasties align with the post-Flood dispersal described in Genesis 10.
5. Joseph in Egypt and the Hyksos
The story of Joseph, as told in Genesis 37–50, places him in Egypt as vizier to Pharaoh. The biblical narrative does not give precise dates, but most traditional chronologies place Joseph’s rise during the Middle Kingdom or Second Intermediate Period (~18th–16th century BCE).
Josephus, in Against Apion (I.14), identifies the Hyksos (a Semitic people who ruled Egypt) with the Israelites. He quotes Manetho, who describes Asiatic invaders who ruled Egypt for 511 years, calling them “Shepherd Kings.”
Josephus interprets Manetho’s account as a distorted memory of the Hebrews’ sojourn in Egypt. Modern scholars suggest the Hyksos were likely unrelated to Joseph himself, but their rule is often used to anchor the timeline of Genesis.

6. Moses and the Osarseph Controversy
Perhaps the most controversial link between Manetho and biblical figures is the association of Moses with Osarseph, found in Against Apion (I.26–31). According to Josephus, Manetho describes a priest named Osarseph who leads a group of lepers and impure people against Egypt.
“This priest, by the name of Osarseph… gave them laws contrary to the customs of the Egyptians… He changed his name to Moses.” (Josephus, Against Apion, I.28)
Josephus furiously rejects this as anti-Jewish propaganda, accusing Manetho of fabricating the account.
Eusebius and Syncellus preserve similar versions of this narrative but with minor variations. Some modern scholars (e.g., Jan Assmann) argue that Manetho’s tale reflects an Egyptian polemical response to the Exodus story—inverting it to cast the Hebrews in a negative light.
Chronologically, Moses is placed by biblical tradition in the 15th or 13th century BCE (depending on interpretation of Exodus 12:40). Manetho’s Osarseph narrative places this rebellion during the reign of Pharaoh Amenophis (possibly Amenhotep III or IV), aligning roughly with traditional late-daters of the Exodus (~13th century BCE).
7. The Purpose of Chronological Harmonization
Why did ancient authors attempt to align Egyptian and biblical timelines? The answer lies partly in the cultural competition between Jewish and Greco-Roman traditions. Authors such as Josephus were eager to demonstrate the antiquity and dignity of the Hebrew Scriptures, often using Egyptian sources like Manetho to legitimize or defend biblical history.
Meanwhile, early Christian chronologists like Eusebius and Africanus sought to develop universal histories, integrating biblical, Greek, Roman, and Egyptian events into a single framework. Their efforts, though speculative, laid the groundwork for medieval and early modern chronologies.
Conclusion
The fragments of Manetho, interpreted and contested by figures like Josephus, Eusebius, and Syncellus, reveal a complex attempt to weave together divergent strands of sacred and secular history. From the enormous spans of time recorded in Egyptian king lists to the compressed genealogies of the Masoretic Text, these chronologies reflect both the grandeur and the ambiguity of humanity’s earliest memories.
Though Manetho never directly chronicled biblical figures such as Adam or Abraham, his dynastic framework became a measuring stick for others to project sacred history onto. Whether through Josephus’ defensive polemic, Eusebius’ harmonizing vision, or Syncellus’ compilation of cosmic time, the echoes of Manetho continue to shape our understanding of the distant past.
The tension between history and myth, between divine ages and dynastic years, is not a flaw of ancient chronology but its very essence—a reminder that time, like memory, is both a record and a narrative.
