Plutarch, Parallele Geschichten 4:

When the Persians were marching with five million men against Greece (1), Leonidas was sent by the Spartans to Thermopylae with three hundred men. While they were eating and drinking there, the barbarian host attacked them; and when Leonidas saw the barbarians, he said, “Eat your lunch now as if you were to dine in the other world [οὕτως ἀριστᾶτε ὡς ἐν Ἅιδου δειπνήσοντες].” And when he rushed against the barbarians, and was pierced by many a spear, he made his way up to Xerxes and snatched off his crown. When he was dead the barbarian king cut out his heart and found it covered with hair. So Aristeides in the first book (2) of his Persian History.

When the Romans were at war with the Carthaginians (3), they dispatched three hundred men and Fabius Maximus as their general. He attacked the enemy and lost all his men, but he himself, although mortally wounded, with a mad rush reached Hannibal and knocked down his crown, and so died with him [συναπέθανεν αὐτῷ]. (4) This Aristeides the Milesian relates.
