Notas:

• Etnográfica:
  This is the feathered wing of a curassow, used as a fire fan.
  An older belief was that as part of the snake bite treatment this fire fan was hung over the bed of the victim. If it swang the person would recover, and if it remained still the person was doomed.
• Gramatical:
  The word ends with the classifying suffix '-up' for roundish objects.
