The authors try to review, critically summarize and enlarge the knowledge about different editions of Hagecius' metoposcopical writing. In the first part of the paper, the date of Hagecius' doctorhood in Bologna, the date of his journey to H. Cardano and relationship of the famous scholar to young Thaddaeus are newly clarified. The next part enriches our knowledge about the role of an unknown personality of Proxenus in the French translation of the book. The third part brings a detailed comparison of the first and second Latin edition. A brief description and evaluation of a newly discovered German translation forms the content of the last part.
