Rio’s Carnival officially begins with the crowing of King Momo. During the ceremony, he is presented with the key to the city. Rey Momo (in Portuguese) is always a large man with a jovial smile and a flamboyant style. You may hear the nickname the Fat King. He kicks off the samba parade. His troupe consists of a royal court and female dancers. The name comes from the Greek god Momus known for his sharp-tongued satire.
