In this article we discuss the results of the re-examination of a terracotta head of supposed Roman origin found in a pre-Hispanic burial offering near Mexico City. A thermoluminescent age test performed in 1995 at the Forschungsstelle Archäometrie in Heidelberg, Germany, set the age limits of the artifact at 1780 ± 400 b.p., which is consistent with the Roman-origin hypothesis. A review of the circumstances of this discovery did not demonstrate any sign of possible post-Columbian intrusion and permits the acceptance of the object as the first hard evidence from Mesoamerica to support pre-Hispanic transoceanic contacts between the Old and New Worlds.
