Lucian Philopseudes sive incredulus 30

[30] “What is that you say?” said Arignotus, with a sour look at me. “Do you think that none of these things happen, although everybody, I may say, sees them?’ “Plead in my defence,” said I,“if I do not believe in them, that I am the only one of all who does not see them; if I saw them, I should believe in them, of course, just as you do.” “Come,” said he, “if ever you go to Corinth, ask where the house of Eubatides is, and when it is pointed out to you beside Cornel Grove, enter it and say to the doorman Tibius that you should like to see where the Pythagorean Arignotus exhumed the spirit and drove it away, making the house habitable from that time on.

[30] ‘What is this I hear?’ asked Arignotus, scowling upon me; ‘you deny the existence of the supernatural, when there is scarcely a man who has not seen some evidence of it?’ ‘Therein lies my exculpation,’ I replied: ‘I do not believe in the supernatural, because, unlike the rest of mankind, I do not see it: if I saw, I should doubtless believe, just as you all do.’ ‘Well,’ said he, ‘next time you are in Corinth, ask for the house of Eubatides, near the Craneum; and when you have found it, go up to Tibius the door-keeper, and tell him you would like to see the spot on which Arignotus the Pythagorean unearthed the demon, whose expulsion rendered the house habitable again.’
