I found this on the Footnotes blog by Jason G. Duesing. You can find the original post here. You can find other posts by Jason on Tolkien here.
Grim was the world and grey last night:The moon and stars were fled,The hall was dark without song or light,The fires were fallen dead.The wind in the trees was like to the sea,And over the mountains’ teethIt whistled bitter-cold and free,As a sword leapt from its sheath.The lord of snows upreared his head;His mantle long and paleUpon the bitter blast was spreadAnd hung o’er hill and dale.The world was blind, the boughs were bent,All ways and paths were wild:Then the veil of cloud apart was rent,And here was born a Child.The ancient dome of heaven sheerWas pricked with distant light;A star came shining white and clearAlone above the night.In the dale of dark in that hour of birthOne voice on a sudden sang:Then all the bells in Heaven and EarthTogether at midnight rang.Mary sang in this world below:They heard her song ariseO’er mist and over mountain snowTo the walls of Paradise,And the tongue of many bells was stirredin Heaven’s towers to ringWhen the voice of mortal maid was heard,That was mother of Heaven’s King.Glad is the world and fair this nightWith stars about its head,And the hall is filled with laughter and light,And fires are burning red.The bells of Paradise now ringWith bells of Christendom,And Gloria, Gloria we will singThat God on earth is come.
Originally published in the 1936 Annual of Our Lady’s School, Abingdon, Tolkien’s “Noel” was unknown and unrecorded until scholars Wayne G. Hammond and Christina Scull discovered it while searching for another poem in June 2013. In May 2015, Our Lady’s School, Abingdon discovered their copy of the Annual and in Feb 2016, news of the discovery was widely reported.
