King of Macedonia in 281–279 BC

Following his departure from Egypt, Ptolemy Ceraunus went to the court of Lysimachus, who ruled Macedon, Thrace and western Asia Minor and who may have been his father in law. Lysimachus’ court was divided on the question of supporting Ceraunus. On the one hand, Lysimachus himself had been married to Ptolemy II's full sister, Arsinoe II, since 300 BC. On the other hand, Lysimachus' heir, Agathocles, was married to Ceraunus' full sister Lysandra. The two sisters were already engaged in conflict over the succession, which Ceraunus' arrival probably exacerbated. Lysimachus ultimately chose to support Ptolemy II and sealed that decision at some point between 284 and 281 BC by marrying his daughter Arsinoe I to Ptolemy II. Continued conflict within Lysimachus' court led to the execution of Agathocles in 282 BC. The course of events and Ptolemy Ceraunus' role in them is unclear. According to one historian, Memnon, it was Ptolemy Ceraunus who carried out the murder of Agathocles. All other sources that mention Ceraunus place him on Agathocles' side in this dispute and report that he accompanied Agathocles' widow, his full sister Lysandra, in her flight to the court of Seleucus I. The murder provoked a massive outcry from Lysimachus' subjects. Seeing an opportunity to intervene for his own gain, Seleucus invaded Lysimachus' kingdom early in 281 BC. This campaign culminated in the Battle of Corupedium, at which Lysimachus was killed and Seleucus annexed his kingdom to his empire. After the Battle of Corupedium, Ptolemy Ceraunus came into Seleucus' control. Seleucus took Ceraunus into his inner circle and perhaps planned to use him as a bargaining chip in the event of conflict with Ptolemaic Egypt. In September 281 BC, Seleucus crossed the Hellespont and prepared to invade Macedon. But as Seleucus was sacrificing at a place called Argos, Ptolemy Ceraunus murdered him, intending to seize control of the territories of his former protector. A series of gold staters and silver tetradrachms minted at Lysimachia appear to belong to this period. They have the same design as earlier coinage of Lysimachus: the head of Alexander the Great with the horn of Ammon on the obverse and a depiction of Athena seated, holding up a Nike on the reverse. The legend of the coins reads ΒΑΣΙΛΕΩΣ ΛΥΣΙΜΑΧΟΥ (of King Lysimachus) and the reverse includes two small symbols: a lion's head, which was the symbol of Lysimachus, and a tiny elephant. Since the elephant was the symbol of Seleucus, these coins have sometimes been connected with the short period of Seleucus' rule over the region between the battle of Corupedium and his assassination. However, Hollstein has argued that these were coins of Ptolemy Ceraunus, intended to present him as the legitimate heir of Lysimachus and in possession of a formidable force of elephants. The issue was very small; Ceraunus never issued coins in his own name. Antigonos Gonatas, whose father Demetrius I Poliorcetes had been king of Macedon from 294 288 BC, attempted to seize control of Macedon, but Ptolemy Ceraunus defeated him in a naval battle and confined him to the city of Demetrias, Thessaly. Ptolemy Ceraunus also made an alliance with Pyrrhus of Epirus, who had controlled the western portion of Macedon from 288 284 BC, ending the threat of attack from him. The alliance freed Pyrrhus to invade Italy to fight against the Roman Republic in the Pyrrhic War. Justin reports that Ceraunus provided Pyrrhus with a large number of troops: 5,000 infantry, 4,000 cavalry, and 50 elephants, and says that the alliance was sealed by the marriage of a daughter of Ceraunus to Pyrrhus. Some scholars have been sceptical of this report, suggesting that Justin has confused Ptolemy Ceraunus with Ptolemy II, since they doubt that Ceraunus could have spared such a large number of troops at this moment. The existence of the marriage is also disputed. If the daughter did exist, her subsequent fate is unknown. Arsinoe II, the widow of Lysimachus, had fled with her young sons after Lysimachus' defeat at Corupedium to Ephesus (which had been renamed Arsinoeia in her honour). The Ephesians rioted against her, forcing her to leave the city and sail to Macedon, where she took control of the city of Cassandreia. Ptolemy Ceraunus was next attacked by a son of Lysimachus and an Illyrian king called Monunius. The son is not certainly identified by the surviving source, but Elizabeth D. Carney argues that it was Ptolemy Epigonos, the eldest son of Arsinoe by Lysimachus. Monunius may have been a king of the Dardanians who took him in after the murder of his younger brothers. This war seems to have occupied Ptolemy Ceraunus for most of 280 BC. When the forces joined battle, Ceraunus was wounded and captured by the Gauls, who killed him, mounted his head on a spear and carried it around the battlefield. When the Macedonians saw that their leader was dead, they fled.

Ptolemy Ceraunus apparently had a daughter, who married Pyrrhus in late 281 or 280 BC. The existence of this marriage is disputed, but if it did take place, Ceraunus must have married her mother around 300 295 BC. Christopher Bennett proposes that she may have been a daughter of Lysimachus, with whom Ptolemy I contracted a number of marriage alliances in those years. Ptolemy agreed to marry Lysimachus' widow Arsinoe II, his own half sister, in late 281 or early 280 BC, as part of a plot to seize the city of Cassandreia and murder her children. It is unclear whether the marriage was actually consummated, but Arsinoe fled Macedon immediately after the wedding.
