This is a mural of El Güegüense or the Machol Ratón, painted on one of the CCBN’s walls. El Güegüense originates from the city of Diriamba, and is a comedic dance that makes fun of the Spanish colonizers. It’s developed into the repertoire of folkloric dances here, and is a symbol of protest by Nicaraguan people.
It is a type of musical drama, with 14 characters, including Spaniards and Nicaraguans. Each character wears colorful masks that exaggerate their personality. Ultimately, it is a musical-dance performance that makes fun of the Spanish and protests their colonial presence.
No one knows who created the dance, and their exist various versions of how it came to be. But, in essence, it’s a rebellious, mischevious, and clever dance.
