Note 4 — Chapter VIII · —THE MAYA: TRIBAL HISTORY
Reading edition
At this point the Kakchiquel annals prove a useful check upon the account given by the Popol Vuh. Tepepul and Iztayul, according to the latter, preceded Quicab, and Quicab was succeeded by Tepepul and Xtayub. It is evident that some duplication has taken place in the Quiché legend, that Tepepul and Iztayul are the same as Tepepul and Xtayub, and that they succeeded Quicab.
