Chronica Naierensis

The Chronica Naierensis or Crónica najerense (originally edited under the title Crónica leonesa) was a late twelfth-century chronicle of universal history composed at the Benedictine monastery of Santa María la Real in Nájera.

In Latin it narrates events from Creation to its own time, with a focus on the Bible, classical history, the Visigothic in Spain, and the kingdoms of Castile and León.

Besides its classical and Biblical authorities, the Chronica Naierensis relied heavily on material culled from the cantares de gesta.

The date of the Chronica's completion was long dated to 1160, but the 1995 critical edition published by Juan Estévez Sola revised the terminus post quem to 1173, for it was not until that year that Pedro Coméstor finished his Historia Scholastica, which the Chronica uses as a source.

The terminus ante quem of the Chronica can be placed in 1194, the earliest date for the composition of the Linage del Cid, which used it as a source.
