Early Life. Nico di Angelo was born sometime in the mid to late 1930's in Venice, Italy, before World War II (before Hades and his brothers took an oath to have no more demigod children). Since Nico was born in Italy and his mother was Italian (the daughter of a diplomat in Washington D.C.), he can speak fluent Italian. He had an older sister named Bianca di Angelo. Around the age of six, Nico visited Diocletian's Palace in Split, Croatia.
