A single rider, poised atop a rearing horse, confronts a writhing, many-headed beast—every line in Slaying the Monster by José Guadalupe Posada is charged with movement and confrontation. The hero’s lance plunges downward, splitting the tangle of serpentine necks and snapping jaws that surge up from the monster’s body. The horse’s flared nostrils and the rider’s determined grip on the reins amplify the urgency of the struggle, while the stylized feathers in the rider’s hat and the geometric trim of the saddle blanket hint at a pageantry both theatrical and deadly.

Light and shadow are rendered in stark black and white, the absence of color sharpening every gesture into a kind of visual shout. The monster’s claws curl helplessly, its heads twisting in every direction, as if the chaos of evil itself is being pinned by sheer will. Created sometime between 1880 and 1910, this print belongs to a world where popular imagery was a powerful tool for storytelling and social commentary. Posada was a master of the cheap broadsheet illustration, and his works—often sold in bustling markets—fed a public hungry for tales of heroism, satire, and the supernatural.

In the late nineteenth and early twentieth centuries, Mexico was a nation in upheaval, and images like this one could serve as both entertainment and allegory. The Metropolitan Museum of Art now holds this print, a testament to how even the most ephemeral art can endure. Look again at the tangle of heads and the unflinching rider—what monsters, real or imagined, might this image have summoned for its first viewers?
