In his article ‘Clouds, Mysteries, Socrates and Plato’ (Antichthon 4 [1970], 13-24), Professor A.W.H. Adkins starts from the agreed fact that certain passages of the Clouds compare entry to the phrontisterion to initiation to mysteries. He argues from this (and here I should not necessarily disagree with him) that Socrates was in the habit of using initiation-language when speaking of philosophy and that Aristophanes, shocked by such blasphemy, ‘used it as one more weapon against Socrates and the New Thought in his Clouds’ (24).
