This is the fourth and last volume in the series, begun in 1941, with the purpose of supplying reliable texts and translations, with critical apparatus, of the three mediaeval Welsh chronicles known to represent three independent versions of a Latin text no longer extant.

Preface.

Brenhinedd y Saesson or The Kings of the Saxons is in large part a third independent version of Brut y Tywysogyon or The Chronicle of the Princes, of which the two main versions have already been edited and translated in this series.
