If you spot an error, have a suggestion, or just want to say hello — we’d love to hear from you.

Amicable reader, we now provide you for the first time with Psellus’s On the Operation of Demons original: "περὶ ἐνεργείας δαιμόνων", which has never before been edited in Greek; furthermore, we provide the notes which we wrote daily as our assigned task 1.

I took the greatest care to ensure you had the author’s very own words as corrected as possible; but even this was not permitted due to the haste of the workers, whom I did not oversee. I corrected what was corrupt in the manuscripts; I explained what was difficult; I restored what was interpolated: all with great trust in you, but greater in myself.
