3rd century BC Babylonian writer, priest and astronomer

Berossus (/b//ə/'/r//ɒ//s//ə//s/) or Berosus (/b//ə/'/r//oʊ//s//ə//s/; Βηρωσσος; possibly derived from , romanized: , "Bel is his shepherd") was a Hellenistic era Babylonian writer, a priest of Bel Marduk and astronomer who wrote in the Koine Greek language, and who was active at the beginning of the 3rd century BC. His original works, including his Babyloniaca, have been lost but fragmentarily survive in some quotations, especially in the writings of the fourth century Christian writer Eusebius. Berossus has recently been identified with Bēl rē’ûšunu, a high priest of the temple Esagila Temple mentioned in a document from 258 BC.

The name Berossus likely originates from a theophoric name whose first component was Bel, meaning "Lord," which was a common title for Marduk. The original name was either either Bēl rē’ûšunu, meaning "the god Bel is their shepherd," or Bēl uṣuršu, meaning "O Bel watch over him!"

Using ancient Babylonian records and texts that are now lost, Berossus published the Babyloniaca (hereafter, History of Babylonia) in three books some time around 290–278 BC, by the patronage of the Macedonian/Seleucid king Antiochus I Soter (during the third year of his reign, according to Diodorus Siculus). Certain astrological fragments recorded by Pliny the Elder, Censorinus, Flavius Josephus, and Marcus Vitruvius Pollio are also attributed to Berossus, but are of unknown provenance, or indeed are uncertain as to where they might fit into his History. Vitruvius credits him with the invention of the semi circular sundial hollowed out of a cubical block. A statue of him was erected in Athens, perhaps attesting to his fame and scholarship as historian and astronomer astrologer. A separate work, Procreatio, is attributed to him by the Latin commentaries on Aratus, Commentariorium in Aratum Reliquiae, but there is no proof of this connection. However, a direct citation (name and title) is rare in antiquity, and it may have referred to Book 1 of his History. He was born during or before Alexander the Great's reign over Babylon (330–323 BC), with the earliest date suggested as 340 BC. According to Vitruvius's work de Architectura, he relocated eventually to the island of Kos off the coast of Asia Minor and established a school of astronomy there by the patronage of the king of Egypt. However, scholars have questioned whether it would have been possible to work under the Seleucids and then relocate to a region experiencing Ptolemaic control late in life. It is not known when he died.

Versions at several removes of the remains of Berossos' lost Babyloniaca are given by two later Greek epitomes that were used by the Christian Eusebius of Caesarea for his Chronological Canons, the Greek manuscripts of which have been lost, but which can be largely recovered by the Latin translation and continuation of Jerome and a surviving Armenian translation. The reasons why Berossus wrote the History have not survived, though contemporaneous Greek historians generally did give reasons for the publication of their own histories. It is suggested that it was commissioned by Antiochus I, perhaps desiring a history of one of his newly acquired lands, or by the Great Temple priests, seeking justification for the worship of Marduk in Seleucid lands. Pure history writing per se was not a Babylonian concern, and Josephus testifies to Berossus' reputation as an astrologer. The excerpts quoted recount mythology and history that relate to Old Testament concerns. As historian and archaeologist W. G. Lambert observes: "Of course Berossus may have written other works which are not quoted by Josephus and Eusebius because they lacked any Biblical interest". Josephus' record of regnal years for these kings is also corroborated by Ptolemy of Alexandria in his Canon, excepting for the fact that the king that reigned between Neglissar and Nabonnedus is omitted by Ptolemy. Nabopolassar = reigned 21 years. Nebuchadnezzar b. Nabuchodonosor = reigned 43 years. Evil Merodach (also called Amel Marduk) = reigned 2 years. (Josephus, elsewhere, contradicts Berossus, saying that Evil Merodach reigned 18 years). Neglissar (Neriglissoor) = reigned 4 years (Josephus, elsewhere, says that Neglissar reigned 40 years, which seems odd that it is a factor of 10). Laborosoarchod (Labosordacus) = reigned 9 months. Nabonnedus (also known as Baltasar) = reigned 17 years, in which year, Cyrus king of Persia and Darius king of Media took Babel (Borsippus) from the Chaldaeans.

Berossus' work was not popular during the Hellenistic period. The usual account of Mesopotamian history was Ctesias of Cnidus's Persica, while most of the value of Berossus was considered to be his astrological writings. Most pagan writers probably never read the History directly, and seem to have been dependent on Posidonius of Apamea (135–50 BC), who cited Berossos in his works. While Poseidonius's accounts have not survived, the writings of these tertiary sources do: Vitruvius Pollio (a contemporary of Caesar Augustus), Pliny the Elder (d. 79 AD), and Seneca the Younger (d. 65 AD). Seven later pagan writers probably transmitted Berossus via Poseidonius through an additional intermediary. They were Aetius (1st or 2nd century AD), Cleomedes (second half of 2nd century AD), Pausanias (c. 150 AD), Athenaeus (c. 200 AD), Censorinus (3rd century AD), and an anonymous Latin commentator on the Greek poem Phaenomena by Aratus of Soloi (ca. 315–240/39 BC). Jewish and Christian references to Berossus probably had a different source, either Alexander Polyhistor (c. 65 BC) or Juba II of Mauretania (c. 50 BC–20 AD). Polyhistor's numerous works included a history of Assyria and Babylonia, while Juba wrote On the Assyrians, both using Berossus as their primary sources. Josephus' records of Berossus include some of the only extant narrative material, but he is probably dependent on Alexander Polyhistor, even if he did give the impression that he had direct access to Berossus. The fragments of the Babylonaica found in three Christian writers' works are probably dependent on Alexander or Juba (or both). They are Tatianus of Syria (2nd century AD), Theophilus Bishop of Antioch (180 AD), and Titus Flavius Clemens (c. 200 AD). Like Poseidonius', neither Alexander's nor Juba's works have survived. However, the material in Berossus was recorded by Abydenus (c. 200 BC) and Sextus Julius Africanus (early 3rd century AD). Both their works are also lost, possibly considered too long, but Eusebius Bishop of Caesaria (c. 260–340 AD), in his work the Chronicon, preserved some of their accounts. The Greek text of the Chronicon is also now lost to us but there is an ancient Armenian translation (500–800 AD) of it, and portions are quoted in Georgius Syncellus's Ecloga Chronographica (c. 800–810 AD). Nothing of Berossus survives in Jerome's Latin translation of Eusebius. Eusebius' other mentions of Berossus in Praeparatio Evangelica are derived from Josephus, Tatianus, and another inconsequential source (the last cite contains only, "Berossus the Babylonian recorded Naboukhodonosoros in his history"). Christian writers after Eusebius are probably reliant on him, but include Pseudo Justinus (3rd–5th century), Hesychius of Alexandria (5th century), Agathias (536–582), Moses of Chorene (8th century), an unknown geographer of unknown date, and the Suda (Byzantine dictionary from the 10th century). Thus, what little of Berossus remains is very fragmentary and indirect. The most direct source of material on Berossus is Josephus, received from Alexander Polyhistor. Most of the names in his king lists and most of the potential narrative content have been lost or completely mangled as a result. Only Eusebius and Josephus preserve narrative material, and both had agendas. Eusebius was looking to construct a consistent chronology across different cultures,

In an isolated report from Vitruvius, it is claimed that Berossus founded a school of astronomy at the Island of Kos, although this is typically dismissed as a later invention. Some historians have suggested that the tale originated to provide a story that creates continuity between Babylonian and Greek astronomy. In 1498, Annius of Viterbo claimed to have discovered lost books of Berossus. These were in fact an elaborate forgery. However, they greatly influenced Renaissance ways of thinking about population and migration, because Annius provided a list of kings from Japhet onwards, filling a historical gap following the Biblical account of the Flood. Annius also introduced characters from classical sources into the biblical framework, publishing his account as Commentaria super opera diversorum auctorum de antiquitatibus loquentium (Commentaries on the Works of Various Authors Discussing Antiquity). One consequence was sophisticated theories about Celtic races with Druid priests in Western Europe.
