 The canonical image of Mariano Moreno is the one from the portrait Mariano Moreno en su mesa de trabajo ( Spanish : Mariano Moreno at his work desk ) . It was done by the Chilean artist Pedro Subercaseaux during the centennial of the May Revolution in 1910 . The historian Adolfo Carranza asked him to design various allegorical pictures of the event . Carranza belonged to the mainstream line of historians who professed great admiration for Moreno , who he described as follows : " He was the soul of the government of the revolution of May , his nerve , the distinguished statesman of the group managing the ship attacked the absolutism and doubt , anxious to reach the goal of his aspirations and his destiny . Moreno was the compass and that also grabbed the helm , as he was the strongest and the ablest of those who came to direct it " . He asked for a picture that was consistent with this image . The portrait depicts him as a friendly man with an open and round face , a wide forehead , and a serene look . Subsequent interpretations , like those of Antonio Estrada , would follow this style , as would portraits of other members of the Junta . However , as this portrait was made a hundred years after the death of the subject , with no known depictions done during his lifetime , it was thus based on the artist 's imagination . It was known that Moreno had clearly visible smallpox scars from the age of eight , but not to the point where they disfigured his face .
