Yaxchilan on the Usumacinta

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

Yaxchilan occupies a bend of the Usumacinta river so pronounced that the site is nearly surrounded by water on three sides, a position that shaped both its defense and its role as a river crossing point between Classic Maya polities on either bank, according to Michael Coe and Stephen Houston's survey of Maya civilization. Its standing architecture, more than eighty structures across the main plaza and the acropolis terraces above it, dates predominantly to the Late Classic period, under the long reign of Itzamnaaj Bahlam III and the subsequent reign of his son Bird Jaguar IV. The city is best known today for its carved lintels, more than fifty survive across its buildings, which record royal accessions, military captures and the bloodletting and vision rites performed by the ruling family, most famously on Lintels 24 and 25 of Structure 23, associated with Itzamnaaj Bahlam III's wife Lady Xoc. Simon Martin and Nikolai Grube's chronicle of the Classic Maya draws heavily on Yaxchilan's own monuments to reconstruct its dynastic sequence, since, as at most Classic Maya sites, the surviving textual record comes almost entirely from monuments the rulers themselves commissioned. The site remained an important power on the Usumacinta into the early ninth century before its monument production ceased along with that of most other Classic Maya lowland cities.
