Book 9
7.3
Philip, the eldest of his sons, shortly after coming to the throne was seized by a wasting disease which proved fatal. Antipater, the next son, murdered his mother Thessalonice, the daughter of Philip, son of Amyntas, and of Nicasipolis, charging her with being too fond of Alexander, who was the youngest of Cassander's sons. Getting the support of Demetrius, the son of Antigonus, he deposed with his help and punished his brother Antipater. However, it appeared that in Demetrius he found a murderer and not an ally.
7.4
So some god was to exact from Cassander a just requital. In the time of Cassander all the ancient circuit of the Theban walls was rebuilt, but fate after all willed that afterwards the Thebans were again to taste the cup of great misfortune. For when Mithridates had begun the war with the Romans, he was joined by the Thebans, for no other reason, in my opinion, except their friendship for the Athenian people. But when Sulla invaded Boeotia, terror seized the Thebans; they at once changed sides, and sought the friendship of the Romans.
7.5
Sulla nevertheless was angry with them, and among his plans to humble them was to cut away one half of their territory. His pretext was as follows. When he began the war against Mithridates, he was short of funds. So he collected offerings from Olympia, those at Epidaurus, and all those at Delphi that had been left by the Phocians.
7.6
These he divided among his soldiery, and repaid the gods with half of the Theban territory. Although by favour of the Romans the Thebans afterwards recovered the land of which they had been deprived, yet from this point they sank into the greatest depths of weakness. The lower city of Thebes is all deserted to-day, except the sanctuaries, and the people live on the citadel, which they call Thebes and not Cadmeia.
