On the death of Thersander, when a second expedition was being mustered to fight Alexander at Troy, Peneleos was chosen to command it, because Tisamenus, the son of Thersander, was not yet old enough. When Peneleos was killed by Eurypylus, the son of Telephus, Tisamenus was chosen king, who was the son of Thersander and of Demonassa, the daughter of Amphiaraus. The Furies of Laius and Oedipus did not vent their wrath on Tisamenus, but they did on his son Autesion, so that, at the bidding of the oracle, he migrated to the Dorians.
On the departure of Autesion, Damasichthon was chosen to be king, who was a son of Opheltes, the son of Peneleos. This Damasichthon had a son Ptolemy, who was the father of Xanthus. Xanthus fought a duel with Andropompus, who killed him by craft and not in fair fight. Hereafter the Thebans thought it better to entrust the government to several people, rather than to let everything depend on one man.
Of the successes and failures of the Thebans in battle I found the most famous to be the following. They were overcome in battle by the Athenians, who had come to the aid of the Plataeans, when a war had arisen about the boundaries of their territory. They met with a second disaster when arrayed against the Athenians at Plataea,479 B.C at the time when they are considered to have chosen the cause of King Xerxes rather than that of Greece.
The Theban people are in no way responsible for this choice, as at that time an oligarchy was in power at Thebes and not their ancestral form of government. In the same way, if it had been while Peisistratus or his sons still held Athens under a despotism that the foreigner had invaded Greece, the Athenians too would certainly have been accused of favouring Persia.
Afterwards, however, the Thebans won a victory over the Athenians at Delium in the territory of Tanagra,424 B.C where the Athenian general Hippocrates, son of Ariphron, perished with the greater part of the army. During the period that began with the departure of the Persians and ended with the war between Athens and the Peloponnesus, the relations between Thebes and the Lacedaemonians were friendly. But when the war was fought out and the Athenian navy destroyed, after a brief interval Thebes along with Corinth was involved in the war with Lacedaemon.394 B.C
Overcome in battle at Corinth and Coroncia, they won on the other hand at Leuctra the most famous victory we know of gained by Greeks over Greeks. They put down the boards of ten, which the Lacedaemonians had set up in the cities, and drove out the Spartan governors. Afterwards they also waged for ten years consecutively the Phocian war, called by the Greeks the Sacred war.
I have already said in my history of AtticaSee Paus. 1.25.3. that the defeat at Chaeroneia was a disaster for all the Greeks; but it was even more so for the Thebans, as a garrison was brought into their city. When Philip died, and the kingship of Macedonia devolved on Alexander, the Thebans succeeded in destroying the garrison. But as soon as they had done so, heaven warned them of the destruction that was coming on them, and the signs that occurred in the sanctuary of Demeter Lawgiver were the opposite of those that occurred before the action at Leuctra.
For then spiders spun a white web over the door of the sanctuary, but on the approach of Alexander with his Macedonians the web was black. It is also said that there was a shower of ashes at Athens the year before the war waged against them by Sulla, which brought on them such great sufferings.
