During which time was Callixeinus alive for during 400 BCE?
Callixenus Callixeinus (Greek: Καλλίξεινος ) was an Athenian politician who lived around 400 BCE, the time of Socrates. After the Battle of Arginusae, Callixeinus argued that the generals who failed to rescue Athenian shipwreck victims should be tried together by the Assembly. Euryptolemus brought a suit ("graphe paranomon") against Callixeinus claiming that the proposal was unlawful, but was forced to drop it in the face of public opinion. At the trial, the remaining generals – two, Aristogenes and Protomachus, had already fled Athens rather than face trial – were found guilty, and sentenced to death. A later rhetorical work by Aelius Aristides claims that Callixenus also proposed that the generals should not be buried, though this is certainly ahistorical.
Plistonicus Plistonicus (or Pleistonicus, Greek: Πλειστόνικος ), was an ancient Greek physician, a pupil of Praxagoras, who therefore lived in the 4th and 3rd centuries BC. He appears to have written a work on anatomy, which is several times mentioned by Galen, who calls him one of the most eminent physicians of his time. He is quoted by Pliny, Athenaeus, Oribasius, and Gariopontus. None of his writings have survived.
