According to Polybius, Antigonus III of Doson literally shouted himself to death.

[**The following takes place in 221 BCE.**] >As it was, [Antigonus](https://upload.wikimedia.org/wikipedia/commons/c/c3/Antigonus_Doson.jpg) marched to Tegea and likewise restored the ancient constitution there, and two days later arrived in Argos at the moment when the Nemean Games were being celebrated. There he was awarded every kind of honour and distinction [**for his victory in the Cleomenean War**] to immortalize his memory, both by the Achaean League and by the individual states, after which he hurried back to Macedonia where he found the Illyrians. >He compelled them to fight a pitched battle and won a victory, but while he was shouting to encourage his troops in the fighting, he exerted himself so violently that he took to vomiting blood, fell into the morbid condition of which this is a symptom, and died soon afterwards, _________________________ **Source:** Polybius, et al. “Events in Greece.” *The Rise of the Roman Empire*.
