Hello, I’ll be your tour guide here at the art museum so I’d like to welcome you to this month’s exhibit of native American pottery. First I’m going to tell you something about the way this pottery was created. Pottery was made all over ancient North America by many different groups of people. One of the earliest of these ancient American cultures was the Hohokam people. They lived in what is now Arizona from about 300 BC to 1500 AD. And it’s their pottery that you will be looking at today. All of the pottery was made from clay. Some objects were for everyday use, like containers for food and water: pots for cooking and mugs, bowls and ladles for drinking and eating. You will also see finger rings and animal-shaped incense burners which we believe were probably used in special rituals. The Hohokam formed their pottery vessels from coils of clay. They shaped them with special tools to create very thin sides on the vessels. Afterwards they painted the pottery with red designs. Actually many of the pieces here have designs right on them that show how the pottery was used. Now I hope you’1l enjoy the beauty and the uniqueness of the Hohokam pottery and that it will give you some interesting insights about the people who created it.
