Mariano Moreno en su mesa de trabajo

"Mariano Moreno en su mesa de trabajo" a painting by Chilean artist Pedro Subercaseaux, portrays Mariano Moreno, the Secretary of War of Argentina's first national government, deeply engrossed in his work at his desk. Commissioned in 1908 by Antonio Carranza for the Argentina Centennial, the artwork aims to depict Moreno working late into the night with a quill in hand, surrounded by papers, emphasizing the gravity of his decisions.

Interestingly, Subercaseaux was not entirely satisfied with his own work. He felt that Moreno appeared less slender than historical descriptions suggested. Despite this, the painting is now housed in the National Historical Museum in Buenos Aires and is widely regarded as the definitive portrayal of Mariano Moreno.
