The feathers are identified as ostrich from their curl or curve at the upper ends, with a slight flare toward the base.

They may be compared with the falcon tail feathers in two-feather crowns such as those of Amun, which are more narrow and straight without curve.

The Atef crown identifies Osiris in ancient Egyptian painting.

Osiris wears the Atef crown as a symbol of the ruler of the underworld.

The tall bulbous white piece in the center of the crown is between two ostrich feathers.
