The Memorabilia (Greek: Ἀπομνημονεύματα, Apomnemoneumata) is a work by Xenophon, containing his reminiscences of Socrates. Unlike his Apology, and that of Plato, it is not intended as an account of Socrates' defence at his trial, although it does attempt to refute the charges put forward on that occasion.
Xenophon is one of only three writers to present contemporary accounts of Socrates, along with Plato and Aristophanes. His view of Socrates has certain features in common with that of later philosophical schools such as the Stoics and Skeptics.
