Plutarch, De Herodoti malignitate
Goodwin, Ed.

Our author in his Third Book, relating the expedition of the Lacedaemonians against the tyrant Polycrates, affirms, that the Samians think and say that the Spartans, to recompense them for their former assistance against the Messenians, both brought back the Samians that were banished, and made war on the tyrant; but that the Lacedaemonians deny this, and say, they undertook this design not to help or deliver the Samians, but to punish them for having taken away a cup sent by them to Croesus, and besides, a breastplate sent them by Amasis.¹ And yet we know that there was not at that time any city so desirous of honor, or such an enemy to tyrants, as Sparta. For what breastplate or cup was the cause of their driving the Cypselidae out of Corinth and Ambracia, Lygdamis out of [p. 341] Naxos, the children of Pisistratus out of Athens, Aeschines out of Sicyon, Symmachus out of Thasus, Aulis out of Phocis, and Aristogenes out of Miletus; and of their overturning the domineering powers of Thessaly, pulling down Aristomedes and Angelus by the help of King Leotychides? —which facts are elsewhere more largely described. Now, if Herodotus says true, they were in the highest degree guilty both of malice and folly, when, denying a most honorable and most just cause of their expedition, they confessed that in remembrance of a former injury, and too highly valuing an inconsiderable matter, they invaded a miserable and afflicted people.
