While Philip went on his expedition against the Byzantines, he left Alexander, then sixteen years old, his lieutenant in Macedonia, committing the charge of his seal to him; who, not to sit idle, reduced the rebellious Maedi, and having taken their chief town by storm, drove out the barbarous inhabitants, and planting a colony of several nations in their room, called the place after his own name, Alexandropolis. At the battle of Chaeronea, which his father fought against the Greeks, he is said to have been the first man that charged the Thebans' sacred band.
And even in my remembrance, there stood an old oak near the river Cephisus, which people called Alexander's oak, because his tent was pitched under it. And not far off are to be seen the graves of the Macedonians who fell in that battle. This early bravery made Philip so fond of him, that nothing pleased him more than to hear his subjects call himself their general and Alexander their king.
But later on, through an unfortunate marriage of Philip with Cleopatra, the niece of Attalus, an estrangement grew up between them. And not long after the brother of Alexander, Pausanias, having had an insult done to him at the instance of Attalus and Cleopatra, when he found he could get no reparation for his disgrace at Philip's hands, watched his opportunity and murdered him.
Alexander was but twenty years old when his father was murdered, and succeeded to a kingdom beset on all sides with great dangers, and rancorous enemies. Hearing the Thebans were in revolt, and the Athenians in correspondence with them, he immediately marched through the pass of Thermopylae, saying that to Demosthenes, who had called him a child while he was in Illyria, and a youth when he was in Thessaly, he would appear a man before the walls of Athens.
When he came to Thebes, to show how willing he was to accept of their repentance for what was past, he only demanded of them Phoenix and Prothytes, the authors of the rebellion, and proclaimed a general pardon to those who would come over to him.
But when the Thebans merely retorted by demanding Philotas and Antipater to be delivered into their hands, he applied himself to make them feel the last extremities of war. The Thebans defended themselves with a zeal and courage beyond their strength, being much outnumbered by their enemies. But when the Macedonian garrison sallied out upon them from the citadel, they were so hemmed in on all sides, that the greater part of them fell in the battle; the city itself being taken by storm, was sacked and razed, Alexander's hope being that so severe an example might terrify the rest of Greece into obedience. So that, except the priests, and a few who had heretofore been the friends and connections of the Macedonians, the family of the poet Pindar, and those who were known to have opposed the public vote for the war, all the rest, to the number of thirty thousand, were publicly sold for slaves; and it is computed that upwards of six thousand were put to the sword. Among the other calamities that befell the city, it happened that some Thracian soldiers having broken into the house of a matron of high character and repute named Timoclea, their captain, to satisfy his avarice, asked her if she knew of any money concealed; to which she readily answered that she did, and bade him follow her into a garden, where she showed him a well, into which, she told him, upon the taking of the city she had thrown what she had of most value. The greedy Thracian presently stooping down to view the place where he thought the treasure lay, she came behind him, and pushed him into the well, and then flung great stones in upon him, till she had killed him.
After which, when the soldiers led her away bound to Alexander, her very mien and gait showed her to be a woman of dignity and high mind, not betraying the least sign of fear or astonishment.
And when the king asked her who she was, she said, "I am the sister of Theagenes, who fought at the battle of Chaeronea with your father, Philip, and fell there in command for the liberty of Greece." Alexander was so surprised, both at what she had done, and what she said, that he could not chose but give her and her children their freedom to go whither they pleased.
After this he received the Athenians into favor. Whether it were, like the lion, that his passion was now satisfied, or that after an example of extreme cruelty, he had a mind to appear merciful, it happened well for the Athenians. Certain it is, too, that in after-time he often repented of his severity to the Thebans, and his remorse had such influence on his temper as to make him ever after less rigorous to all others. And it was observed that whatsoever any Theban, who had the good fortune to survive this victory, asked of him, he was sure to grant without the least difficulty.
Soon after, the Greeks being assembled at the Isthmus, declared their resolution of joining with Alexander in the war against the Persians, and proclaimed him their general. While he stayed here, many public ministers and philosophers came from all parts to visit him, and congratulated him on his election, but contrary to his expectation, Diogenes of Sinope, who then was living at Corinth, thought so little of him, that instead of coming to compliment him, he never so much as stirred out of the suburb called the Cranium, where Alexander ran across him lying at full length in the sun. When he saw so much company near him, he raised himself a little, and vouchsafed to look upon Alexander; and when he kindly asked him whether he wanted any thing, "Yes," said he, "I would have you stand from between me and the sun." Alexander was so struck at this answer, and surprised at the greatness of the man, who had taken so little notice of him, that as he went away, he told his followers who were laughing at the moroseness of the philosopher, that if he were not Alexander, he would choose to be Diogenes.
