quiquemi. Yn quanaca q’[ui]qua ça[n] no yehuatl mocuepaz. (Anales de Juan Bautista [ADJB], f. 8r–8v) = those who eat the meat of cows will become cows. Those who eat the meat of pigs will become pigs. Those who eat lamb shall turn into lambs, and likewise those who wear woolen cloaks. Those who eat chicken will become that.”

In many of the documents in the corpus, a cow is called a vaca (or baca, or vaquilla, etc.), whereas huacax, originally the same word, is often an ox. Thus possibly the reference is to an ox in a testament from the Toluca region.
