A skull opens to reveal a living face in this intriguing mask from Mexico. "Part represents life, part represents death. This exemplifies the ancient Mesoamerican concept of duality," artisan Angel Cerón explains. Day and night, hot and cold, dark and light — this thought was present in almost all philosophical and religious ideas, extending as far south as the Andes. "I was inspired by a mask found in Tlatilco, in the State of Mexico. However, my version is quite different," the artisan says.
