The king had been sitting in darkness for more than 1,400 years. Half of his finely carved face was missing when the archaeologists found him, but his elaborate headdress and badges of rank were still whole. He stared, one-eyed, into the dim tunnel the visitors had excavated inside one of the largest monuments in the ancient Maya city of Holmul, located in what is now northeastern Guatemala. Hieroglyphs near the figure spelled out his name: Och Chan Yopaat, or “Storm God Enters the Sky.”
