So I call this work Eranistes or Polymorphus. I shall write it in the form of a dialogue with questions and answers, propositions, solutions, and antitheses, and all else that a dialogue ought to have. I shall not insert the names of the questioners and respondents in the body of the dialogue as did the wise Greeks of old, but I shall write them at the side at the beginning of the paragraphs. They, indeed, put their writings in the hands of readers highly and variously educated, and to whom literature was life. I, on the contrary, wish the reading of what I write, and the discovery of whatever good it may give, to be an easy task, even to the illiterate. This I think will be facilitated if the characters of the interlocutors are plainly shown by their names in the margin, so the disputant who argues on behalf of the apostolical decrees is called “Orthodoxos,” and his opponent “Eranistes.” A man who is fed by the charity of many we commonly call “Beggar;” a man who knows how to get money together we call a “Chrematistes.” So we have given our disputant this name from his character and pursuits.
