A volume containing religious songs and carols, in Welsh, of the 17th and 18th centuries. The authors were mostly natives of the Teifi Valley in Cardiganshire, where the book was written c. 1720; however, pp. 226-34 and 245-344 are in later hands. Many of the compositions were written by Evan Griffith of Twrgwyn, Cardiganshire. Dates of songs are incorporated in the last lines, but the author's meaning is not always certain and the dates in the latter portion cannot be relied upon. In some cases, the author's name has been obtained from Cwrtmawr MS 45.
