If you want to know who you are and where you come from, follow the maiz."" That was the advice given to author Roberto Cintli Rodriguez when he was investigating the origins and migrations of Mexican peoples in the Four Corners region of the United States.

Follow it he did, and his book Our Sacred Maiz Is Our Mother changes the way we look at Mexican Americans. Not so much peoples created as a result of war or invasion, they are people of the corn, connected through a seven-thousand-year old maiz culture to other Indigenous inhabitants of the continent. Using corn as the framework for discussing broader issues of knowledge production and history of belonging, the author looks at how corn was included in codices and Mayan texts, how it was discussed by elders, and how it is represented in theater and stories as a way of illustrating that Mexicans and Mexican Americans share a common culture.

Rodriguez brings together scholarly and traditional (elder) knowledge about the long history of maiz/corn cultivation and culture, its roots in Mesoamerica, and its living relationship to Indigenous peoples throughout the continent, including Mexicans and Central Americans now living in the United States. The author argues that, given the restrictive immigration policies and popular resentment toward migrants, a continued connection to maiz culture challenges the social exclusion and discrimination that frames migrants as outsiders and gives them a sense of belonging not encapsulated in the idea of citizenship. The ""hidden transcripts"" of corn in everyday culture-art, song, stories, dance, and cuisine (maiz-based foods like the tortilla)-have nurtured, even across centuries of colonialism, the living maiz culture of ancient knowledge.
