This is an Aztec earring, and it's decorated, both inside and out.
★
In their design, we can see three characters embanked, represented with shields and weapons. Their ornaments, their faces and the action of throwing darts have led to them being linked to Tlahuizcalpantecuhtli, the Lord of the Dawn, one of Venus' manifestations.
For the ancient Mexicans, Venus had a powerful presence: when it disappeared from the sky it was thought to descend into the underground world of the dead, to then reappear and release its rays like an arrowhead.
In addition, the end of the earring forms a disk that represents the Sun, bringing together in one piece different elements of its own worldview.
Body modifications and
adornments were very common in various cultures in America; but this earring is unique, as we know very few like it in the world. These were represented in colonial codes, and appear as part of the peace and war outfits of rulers and high dignitaries or as gifts from rulers to prominent members of the nobility.
