A volume containing poetry and essays mostly in Welsh, 1830-1856, by Rowland Thomas ('Idris Ddu', 1789-1856) of Merthyr Tudful, co. Glamorgan, and transcripts by him of poetry by contemporary local poets. Many of the compositions were entered for competition at eisteddfodau held in Merthyr Tudful, Aberdâr, Hirwaun and elsewhere and reflect the culture and radicalism which flourished in the area during the mid-nineteenth century. The volume also contains brief notes by Rowland Thomas's great-grandson, Elias Thomas (d. 1951), of Merthyr Tudful.
