Step-by-step explanation:
The material used to make the Ruler's feather headdress (probably of Motecuhzoma II) from Mexica (Aztec) in 1428-1520 C.E. was feathers (quetzal and cotinga) and gold.
According to historical records and artifacts, the headdress had over 400 tail feathers from the Quetzal and other feathers from the Cotinga, Spoonbill, and Cuckoo, all attached to a net of fibers. The front of the headdress was adorned with gold, including a bird's beak made of gold.
Featherwork was a highly prestigious art form in Aztec culture. Skilled feather artists, called amantecas, used various techniques such as sewing, wrapping with agave cord, gluing, and crimping to work with the feathers and attach them.
