Different cultures have different rituals for honoring their dead. In Mexico and other Spanish-speaking countries, it is Dia de los Muertos or Day of the Dead. During the celebration, ancestors and other loved ones are remembered with altars or ofrendas (offerings) that are decorated with the deceased’s pictures and favorite foods as well as calaveras (skulls made from sugar). The Museum of Sonoma County will be displaying examples of these altars and other Day of the Dead art at the Dia de los Muertos Free Family Festival. In addition to art and altars, the afternoon will include family-friendly activities, and traditional Mexican dances performed by Paquiyollotzin, Ballet Folklorico of Petaluma. The festivities will happen on October 1, noon–4 p.m., at the museum in Santa Rosa (dance performances 2–3 p.m.). Find out more at museumsc.org.
