Corn is a symbol of nourishment, the staff of life, and is significant to many tribes. Corn is regarded as a gift from the Great Spirit, therefore it serves as both nourishment and a ceremonial item. The Iroquois called it "the food that sustains all things." It is used in prayers to God and is important in rituals. When harvesting, only one ear of corn should be taken from each plant to keep its population strong. Native Americans believe that corn has spiritual power. They make an effigy of corn and burn it during the harvest season to bless the crop and bring good luck for the next year. The Sioux burned an image of corn before every battle to give them victory. When Europeans arrived in North America, they saw the importance that Native Americans placed on corn and tried to persuade them to switch their crops. They gave corn new names they thought were more appealing: "Maize" came from the Aztec language and means "food of the gods." Today, corn is still important to many Indians. During the harvest season, they pray for a good crop and offer tobacco. The history of corn shows that it is valuable not only as food but also as a tool for prayer and sacrifice. Today, corn remains a vital part of American culture and cuisine.
