Socrates (; ; – 399 BC) was an ancient Greek philosopher from Classical Athens, perhaps the first Western moral philosopher, and a major inspiration on his student Plato, who largely founded the tradition of Western philosophy. An enigmatic figure, Socrates authored no texts and is known mainly through the posthumous accounts of classical writers, particularly his students Plato and Xenophon.

Amyrtaeus of Sais ( , a Hellenization of the original Egyptian name Amenirdisu) is the only pharaoh of the Twenty-eighth Dynasty of Egypt and is thought to be related to the royal family of the Twenty-sixth Dynasty (664–525 BC). He ended the first Persian occupation of Egypt (i.e. the Twenty-seventh Dynasty: 525–404 BC) and reigned from 404 BC to 399 BC. Amyrtaeus' successful insurrection inaugurated Egypt's last significant phase of independence under native sovereigns, which lasted for about 60 years until the Persians conquered the country again.
