 The earliest history of the codex is unknown.It is named after Gabriel Fejérváry (1780–1851), a Hungarian collector, and Joseph Mayer (1803–1886), an English antiquarian who bought the codex from Fejérváry.In 2004 Maarten Jansen and Gabina Aurora Pérez Jiménez proposed that it be given the indigenous name Codex Tezcatlipoca, from the Nahuatl name of the god Tezcatlipoca (who is shown, with black-and-yellow facial striping, in the centre of its first page), although it is not certain that its creators were Nahuas.
