This is a round pot with wavy line decoration.
It is from grave B230 at el-Amra. This squat shape is one type of decorated pottery found in graves. The painted decoration may be meant to represent a carrying sling made of cord. Pottery jars in graves might have held real food. The jar could also represent the food that would be stored in that sort of jar. Thus an empty grain jar could still mean that the dead person had grain to make bread in the Afterlife. This is a jar. It is made from clay. It is at least 5,100 years old, dating to the Pre-dynastic Period (about 5500-3100 BCE).
