Two 18th century transcripts of Brut y Tywysogion. One in the hand of Rev. Evan Evans (Ieuan Fardd) and copied from the Red Book of Hergest. The other bears no mark of authorship, but the hand is very similar to the first and has been transcribed from a different version.
Also, a published volume of the work, 1860, which was the working copy of Sir John Lloyd, containing his marginal annotations and corrections.
