Brown University’s Stephen Houston and a team of leading researchers in anthropology and Maya archeology methodically verify the authenticity of the oldest known manuscript in ancient America.

PROVIDENCE, R.I. [Brown University] —The Grolier Codex, an ancient document that is among the rarest books in the world, has been regarded with skepticism since it was reportedly unearthed by looters from a cave in Chiapas, Mexico, in the 1960s.

But a meticulous new study of the codex has yielded a startling conclusion: The codex is both genuine and likely the most ancient of all surviving manuscripts from ancient America.

Stephen Houston, the Dupee Family Professor of Social Science and co-director of the Program in Early Cultures at Brown University, worked with Michael Coe, professor emeritus of archeology and anthropology at Yale and leader of the research team, along with Mary Miller of Yale and Karl Taube of the University of California-Riverside.
