Professor Thomas Gwynn Jones, C.B.E. (1871-1949)
The text of this carol was written by the poet Thomas Gwynn Jones (1871-1949), who was Professor of Welsh at University College, Aberystwyth. His reform of the Eisteddfodd in 1902 is credited with putting Wales back in touch with its medieval past. The tune, an old Welsh folksong, "Hir oes i Fair" ("Long life to Mary"), was arranged by Sir Henry Walford Davies.
