Poporo is a device used by indigenous cultures in present and pre-Colombian South America for storage of small amounts of lime. It is constituted by two pieces: the receptacle, and the lid which includes a pin that is used to carry the lime to the mouth while chewing coca leaves. Since the chewing of coca is sacred for the indigenous people, the poporos are also attributed with mystical powers and social status.
In Colombia, poporos are found in archeological remains from the Chibcha, Muisca, and Quimbaya cultures among others. The materials used in the early periods are mainly pottery and carved stone. In classic periods gold and tumbaga are the most frequent: an example of this is the Poporo Quimbaya exhibited in the Gold Museum which is a national symbol. At the present time, the indigenous people of Sierra Nevada de Santa Marta still use poporos made with the dried fruits of a plant of genus cucurbita (totumo), in the traditional way.
One particularly famous poporo, the Poporo Quimbaya, is a precolumbian artpiece of the classic quimbaya period, currently exhibited in the Gold Museum in Bogotá, Colombia. Its primary use was as a ceremonial device for chewing of coca leaves during religious ceremonies. It was made around 300 CE with a lost-wax casting process.
It is believed that the artpiece was stolen from a burial chamber in the early 1930s, on Loma del Pajarito ("Birdie Hill") near Yarumal in the Antioquia department, where, at the time, the grave robbing of indigenous tombs was very common, often ending with destruction of important archeological pieces in order to extract the gold.
In 1939 the Republic Bank, purchased the poporo, as an effort to preserve it from destruction. This began a larger project of preservation of precolumbian goldwork that allowed the creation of Gold Museum.
The Poporo Quimbaya is an unusual piece, made of tumbaga, with oddly minimalistic lines, that give it a modern look. It is one of the most recognized precolumbian artpieces, being often used as a symbol of the indigenous precolumbian culture. It has been depicted in the Colombian currency, in coins and bills.
