Seleucia on the Tigris continues to be Seleucus’s capital for the eastern satrapies.

He installs his son Antiochus here as viceroy in about 293 BCE, the vast extent of the empire seeming to require a double government. (It has been written of Seleucus that "few princes have ever lived with so great a passion for the building of cities. He is reputed to have built in all nine Seleucias, sixteen Antiochs, and six Laodiceas.")

Papirius Cursor is unanimously decreed a triumph, and a period of seven days thanksgiving is declared in his honor.

He sets up a sundial, the first of its kind in Rome, in the temple of Quirinus.

The cult of Venus had begun in Ardea and Lavinium, Latium.

On August 18, 293 BCE, her temple, the oldest-known, is built in Rome, and August 18 becomes a festival called the Vinalia Rustica.

Hellenic culture heavily influences the Getae, especially the ruling class, from about 300 BCE.

One Basileus Dromichaites, having organized the Getae of the Lower Danube into a state by about 300 BCE, repulses an attack by Lysimachus.

Hereafter, native Getian leaders protect the coastal urban centers that have developed from Greek colonies.

Agathocles is sent by his father against the Getae in about 292 BCE but is defeated and taken prisoner.

He is kindly treated by Dromichaetes, and sent back to his father with presents; but Lysimachus, notwithstanding, marches against the Getae, and is taken prisoner himself.

He too is also released by Dromichaetes, who received in consequence the daughter of Lysimachus in marriage.

According to some authors it was only Agathocles and according to others only Lysimachus, who was taken prisoner.

Antiochus is appointed co-regent in 292 BCE, when an invasion of nomads threatens the eastern possessions of his father's realm (between the Caspian and Aral seas and the Indian Ocean).

The danger to Rhodes from Demetrius the Beseiger is now long past, and Chares of Lindos, a pupil of Lysippus, begins his commission to construct the Rhodians’ offering of thanks to Helios, a bronze statue of the nude young god wearing a sun-ray crown and looking out to sea.

Ptolemy, adhering to a defensive foreign policy, has secured Egypt against external enemies and expanded it by means of directly controlled foreign possessions and hegemonic administrations.

He has not, however, neglected to devote attention to the internal organization of the country and to provide for a successor, in 290 making his third wife Berenice queen of Egypt.

The mostly coastal cities of Aetolia, a district of Greece that lies north of the Gulf of Corinth and is bordered on the east by Mount Oxya and on the west by the Achelous River, had formed the Aetolian League in the fourth century BCE.

Now a strong confederacy, the league, having successfully resisted invasions by Macedon in 322 and 314-311, has rapidly grown in strength during the ensuing period of Macedonian weakness, …

…expanding into Delphi (center of the Amphictyonic Council) and …

…allying with Boeotia in about 290 BCE; the Aetolian League will become a major opponent of Macedon and of the soon-to-be-reconstituted Achaean League.

The exhausted Samnites finally conclude a peace in 290 BCE with the Romans, who allow their valorous opponents to become Roman allies, not subjects, as civitas sine suffragio.

The Romans are now the dominant power in Italy.
