Astacus (Bithynia)

Astacus /ˈæstəkəs/ (Greek Ἀστακός Βιθυνίας) is an ancient city in Bithynia; it was also called Olbia /ˈɒlbiə/. Stephanus of Byzantium records an aetiological myth that it was founded by Astacus, son of Poseidon and the nymph Olbia.

Strabo wrote that the city was founded by the Megarians together with the Athenians.[1] On the other hand, Diodorus Siculus mention only the Athenians[2] while the Pomponius Mela and the Photios I of Constantinople only the Megarians.[3][4] The city was a member of the Delian League.[5]

From the city, the Gulf of Astacus took its name.[1][6]

The traditional date of the founding is 712/11 BC, the first year of the 17th Olympiad.[7] However, "Diodorus Siculus" (aka "Library of History"), Book XII, Chapter 34, writes that in the year 435 BCE "And while these events were taking place [the battle of the Athenians on the isthmus near Pallenê against the Potidaeans] the Athenians founded in the Propontis a city which was given the name of Astacus." (Perhaps Diodorus was incorrect.)

Polyaenus wrote that at some point Clearchus of Heraclea, besieged the city.[8]

In Historia Augusta is written that at some point Scythians invaded Bithynia and set fire at the city and plundered it cruelly.[9]

King Zipoetes I of Bithynia made two attempts to absorb Astacus into his kingdom: in 315 BC he was defeated by succors sent by Antigonus Monophthalmos. In 301 BC, he was successful, but the city was destroyed in the war.

Nicomedes I, son of Zipoetes, founded a new city to replace Astacus across from its former location, which he named Nicomedia after himself, bringing some of the Astacan cults to the new site. Nicomedia remained the capital of Bithynia, and became one of the great cities of the Roman east; the Emperor Diocletian made it his usual capital.

Its site is located near the modern Baş İskele.[10][11]

(And on the gulf itself there was also a city Astacus, founded by the Megarians and Athenians and afterwards by Doedalsus; and it was after the city Astacus that the gulf was named. It was razed to the ground by Lysimachus, and its inhabitants were transferred to Nicomedeia by the founder of the latter.)
