'Dies Irae'.
Degreed in fine arts, Maxime Thierry (or simply, Max), has done several artistic jobs such as storyboard artist and letterer. He did his first comics on the internet. He then teamed up with Roger and Isabelle Seiter to start the series 'Dies Irae' at Casterman in 2003.
He should not be confused with Spanish comic artist Max (1956), nor with German comic artist Max (1966) or French comic artist Max (1957).
