Jueves Lardero
In Italy Mardi Gras is called Martedì Grasso (Fat Tuesday). It's the main day of Carnival along with the Thursday before, called Giovedí Grasso (Fat Thursday), which ratifies the start of the celebrations. The most famous Carnivals in northern Italy are in Venice, Viareggio and Ivrea, while in the southern part of Italy the Sardinian Sartiglia and the intriguing apotropaic masks, especially the mamuthones, issohadores, s'urtzu (and so on), are more popular, belonging to a very ancient tradition. Ivrea has the characteristic "Battle of Oranges" that finds its roots in medieval times. The Italian version of the festival is spelled Carnevale.
