For more than a thousand years, a cemetery on the banks of the Rio Grande Coclé in Panama lay undisturbed, escaping the attention of gold seekers and looters. The river flooded in 1927, scattering beads of gold along its banks. In 1940, a Penn Museum team led by archaeologist J. Alden Mason excavated at the cemetery, unearthing spectacular finds—large golden plaques and pendants with animal-human motifs, precious and semi-precious stone, ivory, and animal bone ornaments, and literally tons of detail-rich painted ceramics. It was extraordinary evidence of a sophisticated Pre-columbian people, the Coclé, who lived, died, and painstakingly buried their dead long ago.
