The decorations incised on this ceramic jar identify it as a product of the Fort Ancient people, a late prehistoric culture living in southern Ohio between 1100 and 450 years ago. Fort Ancient people were Ohio's original farmers, growing crops of corn, beans, and squash, and thrived in southern Ohio and northern Kentucky. Villages were made up of a number of circular or rectangular houses surrounding an open plaza. The Fort Ancient people continued to build small burial mounds, but gradually shifted to burials in a cemetery area with no mounds. The jar measures approximately 6.5" (16.51 cm) in diameter and is 5.5" (13.97 cm) tall.
