The ceremony known as Despacho a Pachamama in Quechua, the language of the Incas, gives participants an opportunity to express gratitude to the Earth, and the land that provides resources for well-being, says organizer Tatiana Calixto, a lecturer in Spanish and GIEU Teaching Fellow in the Department of Romance Languages and Literatures.It consists of a series of offerings (seeds, candy, grains and others) that are presented with reverence and gratitude to the Earth. The event also will include video presentations about various aspects of the tradition. “I’ve performed this ceremony with my students in my classes, and they compare it to Mother’s Day,” Calixto said. “I totally agree, since we celebrate a special day by returning to our mothers, perhaps presenting a gift to them, and doing something special for everything that they do for us.”The celebration will be held 5-7 p.m. Friday (April 22) in Room 2435 of North Quad. Calixto says this room provides the perfect space for the event. “For the indigenous peoples?Quechua, Aymara, Arhuaco, Mapuche and many more in the world?the planet is their temple and home. We should learn from that.” In addition to Calixto, other organizers include North Quad Programming, the Language Resource Center and the Department of Romance Languages and Literatures. Location: North Quad, 105 South State St., Ann Arbor.
