Kukulkan
The feathered serpent of the Yucatec Maya, carved as serpent heads at the foot of the great pyramid at Chichén Itzá. Around the spring and autumn equinoxes, crowds gather there to watch a serpent of sunlight form on the stairway.
Meaning
Kukulkan is the Yucatec Maya name for the Feathered Serpent, the being K’iche’ Maya call Q’ukumatz, as the Smithsonian’s National Museum of the American Indian (NMAI) gives the names. In central Mexico the same serpent was Quetzalcoatl. In the K’iche’ creation story, the Popol Vuh, the Feathered Serpent is one of the creators who wanted to make human beings who could “keep the days”. At Chichén Itzá in Yucatán the image is in stone: the pyramid called El Castillo, which UNESCO also calls the Temple of Kukulkan, has serpent heads at the foot of its north stairway, and at what was probably the main door of the temple on top, facing north, two columns in the form of feathered serpents can still be made out. Orlando Casares Contreras of the INAH in Yucatán and his co-authors call the pyramid an emblem of Maya culture in Mexico today.
Origin and history
The oldest written account is a Spanish colonial one. Diego de Landa, the friar who wrote the Relación de las cosas de Yucatán, recorded that “it is the opinion among the Indians” that a great lord called Cuculcan reigned with the Itzá who settled Chichén Itzá, that he came from the west, and that the main building there, also called Cuculcan, proved it. Landa added that when Cuculcan founded Mayapán, the people there named its largest temple Cuculcan too, “like that of Chichén Itzá”.
Where Kukulkan came from is still argued over. UNESCO’s description of Chichén Itzá gives “the most common version”: the king of Tula, Ce Acatl Topiltzin Quetzalcoatl, “or Kukulkan as the Maya translated the name”, took the city between 967 and 987. Peter Schmidt, who directs the INAH’s archaeological project at Chichén Itzá, calls these “Toltecs” one of the hardest questions about the city. The shared features with central Mexico between about 800 and 1200 are undeniable, he writes, but there is no clear evidence whether they come from common roots or from migration or conquest, and friars who had heard similar stories in central Mexico mixed them with Yucatec ones, so that it is “almost impossible” to separate tradition from interpretation. The archaeologist Blas Castellón Huerta counts Kukulkan and the K’iche’ Gucumatz among many figures who took on the feathered serpent’s attributes as priest and hero, and says where and how that happened “is still a matter of debate”.
The serpent of light on the stairway
The archaeologists Ivan Šprajc and Pedro Francisco Sánchez Nava describe what thousands of visitors come to see each equinox, above all in spring. In the late afternoon the stepped edges of the pyramid throw a wavy shadow on the west side of the north stairway’s balustrade, leaving triangles of light, so that a rattlesnake seems to slide down to the carved serpent head at the bottom. People call it the descent of Kukulkan. Jean-Jacques Rivard and Luis Arochi first described it in the 1960s and 1970s as an equinox event, and since then crowds have grown “enormously”, Šprajc and Sánchez Nava write. UNESCO records at least 3,500 visitors a day at the site, and up to 8,000 in the high season.
Was the pyramid built for the equinox?
The archaeoastronomers disagree. Orlando Casares Contreras of the INAH in Yucatán, with Ismael Arturo Montero, Jesús Galindo Trejo and David Wood Cano, holds that the light effect was one of the aims of the pyramid’s design and orientation, though it can be seen for several days either side of the equinox. In an earlier article Montero, Galindo and Wood read the seven triangles as the seven directions of Mesoamerican thought, and note that the same play of light falls on the south stairway in the morning, where there is no serpent head.
Šprajc and Sánchez Nava had the effect photographed every day from 15 to 29 March 2017. It barely changed across those fifteen days; the seventh triangle appeared days before the equinox and stayed for days after, so it could not mark the day. They ask whether the effect was intended at all, and trace the equinox idea to Western astronomy “uncritically projected” onto the past: no Maya building has been found reliably aligned to the equinoxes. At Mayapán, where Landa said the largest temple was also named Cuculcan, a similar pyramid, also called El Castillo, shows a comparable effect for about a month either side of the December solstice, so it could not fix a date either.
Kukulkan and Quetzalcoatl
They are the same feathered serpent under two peoples’ names, and the two pages here tell the Maya and the Aztec sides. Montero, Galindo and Wood write that the feathered serpent, “Kukulcán, or Quetzalcóatl in the mythology of central Mexico”, may have been the civilising god who gave people the calendar.
