January 28, 2014, cast a dark shadow over European comics. On that day, the Belgian comic artist Philippe Delaby passed away at the age of just 53 due to heart failure. His passion was primarily for historical themes, which led to the development of "Knights of the Lost Land" and especially "Murena," becoming his most important series. Not only was the quality of "Murena" outstanding, but its success was remarkable as well. Together with his close friend and screenwriter Jean Dufaux, he delved deep into the Roman Empire, creating a vibrant historical drama that oscillates between fact and fiction, which is already considered a modern classic. This sketchbook provides insight into the artistic creation process of "Murena," but even more so, it pays tribute to one of the best artists of Franco-Belgian comic art—a small thank you for a great work.
