His research was initially guided by previously published research as well as photographic documentation of molds and glyphs. Most of the photographs were supplied by Alfred Maudslay, an English archaeologist who made significant contributions to Central American archeology. His most important breakthrough occurred when he came across the "Relación de las cosas de Yucatán" by Bishop Diego de Landa, written in 1566 but never published until 1864 when it was uncovered by the French antiquarian, Brasseur de Bourbourg.
