The police arrested Apollinaire and Picasso, both foreigners and, more threatening, both well-known advocates of modern art’s revolutionary power. Apollinaire often proclaimed, “in art, one has to kill one’s father,” and had signed a petition in support of burning down the Louvre. Picasso himself had advocated against museums as “petty and ridiculous things.” While such words were fine as provocations of young artists and poets in the cafes of Montmartre, they were more threatening in those hot, autumn days when all of Paris and much of Europe was searching for “Mona Lisa.” In court, Picasso claimed his innocence. He said he had no idea the statuettes he owned were stolen from the Louvre. Neither Picasso nor Apollinaire were ever tried for the theft of “Mona Lisa.” Da Vinci’s painting would emerge two years later in a hotel room in Florence, Italy.
