Palenque: House E of the Palace [January 1, 2004]

"House E, the first structure built on the upper terrace of what was to become the Palace at Palenque, was built by Lady Kanal Ikal [Pacal the Great's Great-Grandmother], thus the Ik glyph-alike openings appear in the walls of this building, as well as all later buildings at Palenque. In the western corridor of this building, there is a dais which served as the accession throne of Pacal as well as all other kings following him."

Merle Greene Robertson, "Sculpture and Murals of the Usumacinta Region," in MAYA (Pallazzo Grassi, Venice), p. 297

The mansard roofs of the palace were decorated with stucco figures, in this instance, a grotesque head.
