MESOAMERICAN EVIDENCE OF PRE-COLUMBIAN TRANSOCEANIC CONTACTS

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 Archaometrie 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.

Acali, Ra 1, and Ra 2: Some conclusions and hypotheses concerning human friction under isolation and stress, with special reference to intelligence and personaiity assessment

Eleven adult volunteers - six females and five males - were left on a small raft in the Atlantic in order to study interpersonal relationships affected by family patterns of behavior, attitudes toward sex, race and racism, nationality, verbal and nonverbal communication, personality and character, intelligence, language, religion, leadership roles, and space. We hoped to gain a better understanding of friction and violence phenomena. The Acali experiment grew out of the more limited raft studies of Ra 1 and Ra 2. Intelligence and personality of the 11 members of the Acali raft expedition of 1973 were assessed by crew members and by shore-based scientists. Predictions concerning the Likely outcome of this long period of unavoidable proximity to 10 other individuals were made by a variety of scientists. Media treatment and views of friends and relatives were also studied. Some of the basic findings of the study were that assessments of both intelligence and personality carried out by these two methods were very different. Practising artists showed better predictive powers concerning the outcome of the voyage than either natural or social scientists. Media treatment influenced the views of the relatives of volunteers. It is suggested that laboratory assessments may not be related to assessed performances under stress, and that further progress in understanding human hostility will depend on a better knowledge of individual interactions.
