The motif of the nine bows, associated with the god Anubis, was used as the seal of the Theban necropolis administration in the New Kingdom (left example). However, the use of faience for the right ring suggests that it was not intended to be used as an official seal, but rather as an apotropaic amulet in a funerary context1
