Códice de Roda

The first two-thirds of the compilation reproduces a single work, Paulus Orosius' Seven Books of History Against the Pagans.

Unique items include a list of Arab rulers and of the Christian kings of Asturias–León, Navarre and France; a chronicle of the Kingdom of Navarre; the Chronicle of Alfonso III; a necrology of the bishops of Pamplona; and the De laude Pampilone epistola.

[2][5] The genealogies in the Roda Codex have played a critical role in interpreting the scant surviving historical record of the dynasties covered.

These include the Íñiguez and Jiménez rulers of Pamplona, the counties of Aragon, Sobrarbe, Ribagorza, Pallars, Toulouse and the duchy of Gascony.

It has recently been suggested that these genealogies, reminiscent of the work of Ibn Hazm, were prepared in an Iberian Muslim context in the Ebro valley and passed to Navarre at the time the codex was compiled.
