Like the Macedonians, they were ruled by Aridaeus, also called Philippus, for seven years after the death of Alexander. Then his successor Cassander ruled over Epirus and the Thessalians for 19 years. After him, his son Philippus [ruled] for 4 months. Then his brothers Antipater and Alexander [ruled] for 2 years and 6 months. And then Demetrius the son of [Antigonus ruled] for 6 years and 6 months. After him, Pyrrhus [ruled] for 4 years and 4 months. Then Lysimachus the son of Agathocles [ruled] for 6 years. [p243] And Ptolemaeus, who was called Ceraunus, [ruled] for one year and 5 months. Then Meleager [ruled] for 2 months. After him, Antipater the son of Lysimachus [ruled] for 45 days. After him, Sosthenes [ruled] for one year. Then there was anarchy for 2 years and 2 months, after which Antigonus the son of Demetrius [ruled] for 34 years and 2 months.
During this time, Pyrrhus won over Antigonus' army and ruled over a few regions, but he lost control of them when he was defeated by Demetrius the son of Antigonus in a battle at Derdia. Shortly afterwards Antigonus died, and his son Demetrius reigned for 10 years. After him, Antigonus, the son of Demetrius who went off to Cyrene and of Olympias the daughter of Pauliclitus of Larisa, [ruled] for 9 years. Antigonus came to the aid of the Achaeans, defeated Cleomenes the king of the Spartans in battle, and liberated Sparta. Therefore the Achaean people honoured him like a god.
After him, Philippus the son of Demetrius reigned for 23 years and 9 months, until he was defeated in a battle in Thessaly by Titus the Roman general. Then the Romans allowed the Thessalians to be autonomous, along with the rest of the Ionians [? Greeks] who had been subject to Philippus. For the first year there was anarchy in Thessaly, but then they started to elect annual leaders from amongst the people.
The first to be elected was Pausanias the son of Echecrates, from Pherae. Then Amyntas the son of Crates, from [?] Pieria; in his year, Titus returned to Rome. Then Aeacides the son of Callas, from Metropolis. Then Epidromas the son of Andromachus, from Larisa, for 8 months only; for the remaining 4 months of the year, the leader was Eunomus the son of Polyclitus, from Larisa. Eunomus was leader again for the whole of the following year. Then Aeacides the son of Callas, from Metropolis, for a second time. Then Pravilus the son of Phaxas, from Scotussa. Then Eunomus [p245] the son of Polyclitus, from Larisa, for a second time. Then Androsthenes the son of Italas, from Gortona. Then Thrasymachus the son of Alexander, from [?] Atrax. Then Laontomenes the son of Damothon, from Pherae. Then Pausanias the son of Damothon. Then Theodorus the son of Alexander, from Argos. Then Nicocrates the son of Paxinas, from [?] Scotussa. Then Hippolochus the son of Alexippus, from Larisa. Then Cleomachides the son of Aeneus, from Larisa. Then Phyrinus the son of Aristomenes, from Gomphi.
In his year, Philippus the king of Macedonia died, and was succeeded by his son Perseus. As we said, Philippus reigned over the Thessalians for 3 years and 9 months, but in all he reigned over the Macedonians for 42 years and 9 months. From the start of the reign of Philippus [Aridaeus] until the death of Philippus the son of Demetrius, that is from the second year of the 114th Olympiad [323 B.C.] until the fifth month of the second year of the 150th Olympiad [179 B.C.] , is a total of 144 years and five months.

[p247] The kings of Asia and Syria after the death of Alexander the Great:
In the 6th year of Philippus Aridaeus, which was the third year of the 115th Olympiad [318 B.C.] , Antigonus became the first king of Asia. He reigned for 18 years, and lived in all for 86 years. He was the most formidable of the kings of that period, and died in Phrygia after all the other rulers attacked him out of fear of him, in the fourth year of the 119th Olympiad [301 B.C.] .
