Finally I became the editor of Antichthon Universalis and made it available to the world. I wrote a foreword and included all data we have about it.
The book can be bought from my shop at Lulu.com. We (Pavel Kolsinski and me) preferred to publish it at a low cost to pay the expenses we had on the investigation of the text.
We still welcome any additional information you could have on the subject, please follow the Antichthon Universalis main page for details on how we can be contacted.
Update: The book cannot be purchased anymore.
