Magnus, pseudonym of Roberto Raviola (May 30, 1939 – February 5, 1996), was an Italian comic book artist, regarded as one of the foremost cartoonists of all time in his country.

Lo Sconosciuto (The Unknown) is an Italian comics series created in 1975 by Roberto Raviola, better known his pseudonym Magnus. It has been translated into English as The Specialist.

The series and its eponymous character was created by Magnus after a series of trips abroad and was defined together with his friend, the singer and writerFrancesco Guccini. It was the first great creation by Magnus after he had left Editoriale Corno and his partnership with writer Max Bunker, with whom he had created famous series such as Kriminal and Alan Ford. Published in July 1975 by Edizioni Del Vascello (Renzo Barbieri‘s publisher), it is considered his finest achievement. The last Sconosciuto story was released in 1984, though a short prologue for another, never published story appeared in 1996 as a dedication to his friend, the cartoonist Franco Bonvicini, who had recently died.
