This is a "Pan Grave" cup.
It is from Deir Rifa. The “Pan-Grave” people were Nubian cattle herders who moved into Upper Egypt in the Hyksos Period – the 15th Dynasty. The name comes from their style of burial in shallow pit-graves.This style of black-topped redware pottery was made by the settlers, who may have been employed as mercenary soldiers and police by the Egyptians. Groups like the ‘Pan-grave’ people brought outside influences to Egyptian pottery, quite apart from trade influences from the surrounding countries. This is a “Pan Grave” cup. It is made from clay. It is between 3,550 and 3,650 years old, dating to the 15th, 16th or 17th Dynasty (1650-1550 BCE) in the Second Intermediate Period.
