This is an example of a Predynastic black-top, red-ware vessel from Abydos, Egypt. Objects like this are characteristic of the Naqada culture. Naqada pottery has been organized into a chronology starting with Egyptologist Sir Flinders Petrie and continuing to the present. It is divided into three periods; this vessel is likely from Naqada I (4400-3500 BCE) or Naqada II (3500-3200 BCE). Pottery from this time is characterized by a thick black ring around the top (created by reduction firing) and more oxygen-exposed red clay below. This is a serving vessel, possibly for the consumption of beer.
