30. Antigonus marched up and took the city without resistance. He treated the Lacedaemonians humanely, and did not insult or mock the dignity of Sparta, but restored her laws and constitution,¹ sacrificed to the gods, and went away on the third day. For he learned that there was a great war in Macedonia and that the Barbarians were ravaging the country. Moreover, his disease was already ill full possession of him, having developed into a quick consumption and an acute catarrh. [2] He did not, however, give up, but had strength left for his conflicts at home, so that he won a very great victory, slew a prodigious number of the Barbarians, and died gloriously, having broken a blood-vessel (as it is likely, and as Phylarchus says by the very shout that he raised on the field of battle. And in the schools of philosophy one used to hear the story that after his victory he shouted for joy, ‘O happy day!’ and then brought up a quantity of blood, fell into a high fever, and so died. So much concerning Antigonus.
