Cronica Walliae (full title: Cronica Walliae a Rege Cadwalader ad annum 1294) is a manuscript of chronological history by Humphrey Llwyd written in 1559. Llwyd translated versions of a medieval text about Wales' history, Brut y Tywysogion, from Welsh and Medieval Latin into English. He also added historical material from Matthew Paris and Nicholas Trivet, as well as from other well known historians. It is the first history of Wales written in English and contains material about ancient rulers, with some material based on legends. Llwyd's work gives a history description of Wales that was originally written in the early part of the sixteenth century by Sir John Prise of Brecknockshire, Wales.
