All Nations, before they began to keep exact accounts of Time, have been prone to raise their Antiquities; and this humour has been promoted, by the Contentions between Nations about their Originals. Herodotus 1 tells us, that the Priests of Egypt reckoned from the Reign of Menes to that of Sethon, who put Sennacherib to flight, three hundred forty and one Generations of men, and as many Priests of Vulcan, and as many Kings of Egypt: and that three hundred Generations make ten thousand years; for, saith he, three Generations of men make an hundred years: and the remaining forty and one Generations make 1340 years: and so the whole time from the Reign of Menes to that of Sethon was 11340 years. And by this way of reckoning, and allotting longer Reigns to the Gods of Egypt than to the Kings which followed them, Herodotus tells us from the Priests of Egypt, that from Pan to Amosis were 15000 years, and from Hercules to Amosis 17000 years. So also the Chaldæans boasted of their Antiquity; for Callisthenes, the Disciple of Aristotle, sent Astronomical Observations from Babylon to Greece, said to be of 1903 years standing before the times of Alexander the great. And the Chaldæans boasted further, that they had observed the Stars 473000 years; and there were others who made the Kingdoms of Assyria, Media and Damascus, much older than the truth.
Some of the Greeks called the times before the Reign of Ogyges, Unknown, because they had No History of them; those between his flood and the beginning of the Olympiads, Fabulous, because their History was much mixed with Poetical Fables: and those after the beginning of the Olympiads, Historical, because their History was free from such Fables. The fabulous Ages wanted a good Chronology, and so also did the Historical, for the first 60 or 70 Olympiads.
The Europeans, had no Chronology before the times of the Persian Empire: and whatsoever Chronology they now have of ancienter times, hath been framed since, by reasoning and conjecture. In the beginning of that Monarchy, Acusilaus made Phoroneus as old as Ogyges and his flood, and that flood 1020 years older than the first Olympiad; which is above 680 years older than the truth: and to make out this reckoning his followers have encreased the Reigns of Kings in length and number. Plutarch 2 tells us that the Philosophers anciently delivered their Opinions in Verse, as Orpheus, Hesiod, Parmenides, Xenophanes, Empedocles, Thales; but afterwards left off the use of Verses; and that Aristarchus, Timocharis, Aristillus, Hipparchus, did not make Astronomy the more contemptible by describing it in Prose; after Eudoxus, Hesiod, and Thales had wrote of it in Verse. Solon wrote 3 in Verse, and all the Seven Wise Men were addicted to Poetry, as Anaximenes 4 affirmed. ‘Till those days the Greeks wrote only in Verse, and while they did so there could be no Chronology, nor any other History, than such as was mixed with poetical fancies. Pliny, 5 in reckoning up the Inventors of things, tells us, that Pherecydes Syrius taught to compose discourses in Prose in the Reign of Cyrus*, and* Cadmus Milesius to write History. And in 6 another place he saith that Cadmus Milesius was the first that wrote in Prose. Josephus tells us 7 that Cadmus Milesius and Acusilaus were but a little before the expedition of the Persians against the Greeks: and Suidas 8 calls Acusilaus a most ancient Historian, and saith that he wrote Genealogies out of tables of brass, which his father, as was reported, found in a corner of his house. Who hid them there may be doubted: For the Greeks 9 had no publick table or inscription older than the Laws of Draco. Pherecydes Atheniensis, in the Reign of Darius Hystaspis, or soon after, wrote of the Antiquities and ancient Genealogies of the Athenians, in ten books; and was one of the first European writers of this kind, and one of the best; whence he had the name of Genealogus; and by Dionysius 10 Halicarnassensis is said to be second to none of the Genealogers. Epimenides, not the Philosopher, but an Historian, wrote also of the ancient Genealogies: and Hellanicus, who was twelve years older than Herodotus, digested his History by the Ages or Successions of the Priestesses of Juno Argiva. Others digested theirs by those of the Archons of Athens, or Kings of the Lacedæmonians. Hippias the Elean published a Breviary of the Olympiads, supported by no certain arguments, as Plutarch 11 tells us: he lived in the 105th Olympiad, and was derided by Plato for his Ignorance. This Breviary seems to have contained nothing more than a short account of the Victors in every Olympiad. Then 12 Ephorus, the disciple of Isocrates, formed a Chronological History of Greece, beginning with the Return of the Heraclides into Peloponnesus, and ending with the Siege of Perinthus, in the twentieth year of Philip the father of Alexander the great, that is, eleven years before the fall of the Persian Empire: but 13 he digested things by Generations, and the reckoning by the Olympiads, or by any other Æra, was not yet in use among the Greeks. The Arundelian Marbles were composed sixty years after the death of Alexander the great (An. 4. Olymp. 128.) and yet mention not the Olympiads, nor any other standing Æra, but reckon backwards from the time then present. But Chronology was now reduced to a reckoning by Years; and in the next Olympiad Timæus Siculus improved it: for he wrote a History in Several books, down to his own times, according to the Olympiads; comparing the Ephori, the Kings of Sparta, the Archons of Athens, and the Priestesses of Argos with the Olympic Victors, so as to make the Olympiads, and the Genealogies and Successions of Kings and Priestesses, and the Poetical Histories suit with one another, according to the best of his judgment: and where he left off, Polybius began, and carried on the History. Eratosthenes wrote above an hundred years after the death of Alexander the great: He was followed by Apollodorus; and these two have been followed ever since by Chronologers.
