The origin of the popular Christmas colors red and green is speculated to be Italy, since the Italian flag's colors are red, green, and white and most of the Christmas traditions we have were usurped from early Pagan people of the 3rd Century.\n\nIn AD 274, Emperor Aurelian decreed December 25 as natalis solis invicti ("birth of the invincible sun"), a festival honoring the sun god Mithras known as Saturnalia. It had been celebrated by Pagans for centuries, but the emperor moved it to this later date.\n\nShortly thereafter, the Church Fathers likewise set the official date for celebrating the birth of Jesus as being December the 25th.\n\nThe Italians today commemorate Christmas for an entire month. Just as in the days of Pagan Rome with Saturnalia, the period between mid-December and early January is one constant celebration.\n\nRich Nativity scenes and the playing of bagpipes by the zampognari (shepards) are very important to the look and feel of Christmas in Italy.
