This ancient Maya city in Yucatán, Mexico is called Uxmal. Macduff Everton (Member 47,306) photographed the site for a book by scholars of Maya culture Linda Schele and Peter Mathews. Macduff spotted this sky of Cumulus over the Northern Building, which has lattices of flower motifs carved onto it and, according to Linda and Peter, motifs that relate to the sky. Squared-off S-shaped symbols (see inset drawing to the left) intersperse the flower lattices, and these are associated with the Mayan word muyal, meaning ‘cloud’. The decorations of the Northern Building appear also to contain a celestial play on words. Spaced out around the structure, in between the flower and cloud symbols, are undulating snakes (see inset drawing to the right). The Mayan word for ‘snake’ is kan, which sounds almost identical to their word for ‘sky’, ka’an. Snakes and cloud symbols therefore suggest a ‘cloudy sky’. For this reason, Linda and Peter argue that the Northern Building was decorated as a flower house in the clouds. Having spent many years studying and documenting Mayan culture, Macduff well knows that the hot tropical climate of Yucatán often gives rise to sky gardens that bloom with Cumulus clouds, which are part and parcel of the life of the Maya, both ancient and contemporary.
