Title: What Child Is This?
Content:  Although written in 1865, "What Child Is This?" was only first published six years later in 1871, when it featured in Christmas Carols Old and New, a "prestigious" and "influential" collection of carols that was published in the United Kingdom. The hymnal was edited by Henry Ramsden Bramley and John Stainer; even though it is not known with certainty who paired the three stanzas from "The Manger Throne" with the music from "Greensleeves", the third edition of The Christmas Encyclopedia by William D. Crump and Stories of the Great Christmas Carols both suggest that Stainer – who was also responsible for "harmoniz[ing] the musical setting" – may have done so.

Title: What Child Is This?
Content:  At the time he was writing the lyrics to "What Child Is This?" in 1865, William Chatterton Dix was working as the manager of an insurance company. He was afflicted by an unexpected and severe illness that resulted in him being bedridden and suffering from severe depression. His near-death experience brought about a spiritual renewal in him while he was recovering. During this time, he read the Bible comprehensively and was inspired to author hymns like "Alleluia! Sing to Jesus!" and "As with Gladness Men of Old". The precise time in 1865 when he wrote the poem "The Manger Throne" is disputed. While the St. Petersburg Times details how Dix penned the work after reading the Gospel for Epiphany that year (Matthew 2:1–12) recounting the journey of the Biblical Magi; Singer's Library of Song: Medium Voice contends that it was actually authored during the Christmas of 1865.
