Leon of Salamis
Greek philosopher

Leon of Salamis (; Ancient Greek: Λέων) was a historical figure, mentioned in Plato's Apology, Xenophon's Hellenica and Andocides' On the Mysteries (1.94). This Leon may also be the renowned Athenian general Leon of the Peloponnesian War.
Plato's and Xenophon's Leon
As part of the Hellenica, the historian Xenophon describes the reign over Athens of the Thirty Tyrants, a ruthless oligarchy under the control of Sparta, Athens' Hellenic rival. Xenophon lists some of the atrocities committed by the Thirty, including "when Leon of Salamis, a man of high and well-deserved reputation, was put to death, though he had not committed the shadow of a crime" (Hellenica Book II).
In the Apology, Plato's Socrates argues that he fears committing injustice more than he fears death. In support of that claim, he cites two incidents in which he, at great personal risk, disobeyed unjust commands of the Athenian government. One of those orders was for him to arrest Leon of Salamis and bring him to the Thirty for execution:
When the oligarchy was established, the Thirty summoned me to the Hall, along with four others, and ordered us to bring Leon from Salamis, that he might be executed. They gave many other orders to many people, in order to implicate as many as possible in their [i.e., the Thirty's] guilt. Then I showed again, not in words but in action, that, if it's not crude of me to say so, death is something I couldn't care less about, but that my whole concern is not to do anything unjust or impious. That government, as powerful as it was, did not frighten me into any wrongdoing.
