 I couldn't find it in any dictionary I have either. A google search turned up only a web hosting company named Apodigm and pages which had this same quote from Chester (including translations into French and Italian which left "apodigm" untraslated). I suspect he made the word up, and either we aren't clever enough or we don't know enough greek to know what he meant by it. 76.20.12.54  22:32, 1 November
