tlacahuacalli (TR25v)

The flames would suggest that this is a funerary carrying frame for a corpse. The fact that the man's eye is closed suggests that he is dead. The Florentine Codex shows a ceremony involving the burning of a funerary bundle (a corpse shrouded in white cotton cloth that is tied on with cords or ropes). An article on "Aztec Burials" in Mexicolore shares further: "The higher up in society, the more likely you were to be cremated, alongside the tools of your trade and other offerings. Once burnt, your ashes would be collected in a pottery vase [as shown in the photograph already shared], which also held the green stone chalchihuitl jewel that would be your soul’s heart on the coming journey. The vase would be buried in a deep hole at your home, covered with food-and-drink offerings."

A comparison with this glyph might be made with the tlecuilli from the Códice Durán, which Marc Thouvenot publishes in one of his vignettes: https://vignettes.sup-infor.com/imagen/DU_02_280r_a.
