Codex Regius is a pen name and label of a pair of two authors from Slovenia and Germany, respectively. One author is a university engineer of chemistry and has spent her time trying to convey the wonders of the Periodic Table to mostly unreceptive students. The other is a graduate of physical engineering and former technical editor. Their SF novel "Horsemen of Mars" has won the award of LiteraturWerkstatt Berlin in 2000 and was nominated for the Kurd-Laßwitz-Award of 2001. In the last 10 years they have been running a freelance translating and editing business, publishing own works that they compose themselves including translations, cover art or page layouting, but they also offer their services to other authors. The two authors of Codex Regius are married to each other and still trying to find a common language.
