Note 51 — Chapter XI · EUTHYPHRON.
Reading edition
Steinhart (Einleitung, p. 199) agrees with the opinion of Schleiermacher and Stallbaum, that the Euthyphron was composed and published during the interval between the lodging of the indictment and the trial of Sokrates. K. F. Hermann considers it as posterior to the death of Sokrates.
I concur on this point with Hermann. Indeed I have already given my opinion, that not one of the Platonic dialogues was composed before the death of Sokrates.
