The Apotheosis of Janaab’ Pakal takes up anew the riddles within a number of Maya hieroglyphic inscriptions first recognized by Floyd Lounsbury. Gerardo Aldana unpacks these mathematical riddles using an approach grounded in a reading of the texts made possible by recent advances in decipherment. Using a history of science methodology, he expands upon (and sometimes questions) the foundational work of archaeoastronomers.
