Chimalcueyo (MH643r)
This black-line drawing of the simplex glyph for Chimalcueyo ("War Shield" of a certain design, attested here as a man's name) shows a round shield with a concentric circle that creates a border. Inside the border is a quincunx shape with four curves and a small circle in the middle. Feathers hang from the bottom of the shield, and squiggly lines of a vague scalloped shape appear on the top.

"Cueyo" is not quite the same shield design as "cuexyo." This is perhaps a less common design, but it compares favorably to the shields in the glyphs Chimalhuilan and Chimalcozauh, below.
This may be a war shield of the ihuiteteyo design, discussed by Frances Berdan and Patricia Anawalt (The Codex Mendoza, 1992, vol. 1, Appendix G). It can come in different colors. Sometimes the symbols on this design are taken for shells. An article by Ian Mursell in Mexicolore and citing the same authors, reminds us that they are down balls, which have associations with death. He also paraphrases John Pohl, saying that the war shield was very personal, it "represented the warrior’s soul, and would generally be burned at the funeral of a dead man." We also learn from The Codex Mendoza: New Insights (2022, 24), that "the tlacuiloque drew and painted a total of eleven ihuiteteyo, one for each one of the rulers of the city."
