Plutarch, Parallele Geschichten 10:

When the Persians were plundering Greece, Pausanias, the Spartan general, accepted five hundred talents of gold from Xerxes and intended to betray Sparta. But when he was detected, Agesilaüs (1), his father, helped to pursue him to the temple of Athena of the Brazen House; the father walled up the doors of the shrine with bricks and killed his son by starvation. His mother (2) also cast his body forth unburied. So Chrysermus in the second book of his Histories.

The Romans in their war with the inhabitants of Latium elected Publius Decius general. A certain poor, but noble, youth named Cassius Brutus wished to open the gates at night for a stated sum of money. He was detected and fled to the temple of Minerva Auxiliaria. Cassius Signifer, his father, shut him in, killed him by starvation, and cast him forth unburied. So Cleitonymus in his Italian History.

(1) Fehler von Plutarch: es muß Kleombrotos heißen.
(2) Theano

Die Geschichte von Pausanias und Kleombrotos wird auch überliefert von Thukydides (I 134), Diodorus Siculus (XI 45, 6), Polyainos (Stratagemata VIII 51) und Cornelius Nepos (Das Leben des Pausanias 5).
