Thou art [hast] gone up on high, To mansions, &c. Emma Toke, née Leslie. [Ascension.] Written in 1851, and contributed anonymously to the Society for Promoting Christian Knowledge Hymns for Public Worship, 1852, No. 61, in 3 stanzas of 4 lines; and again in later editions of the same collection. Its use is very extensive in most English-speaking countries. The text is seldom altered, a marked instance to the contrary, however, being the Hymnary, 1872. In Hymns Ancient & Modern, 1861, stanza i., 1. 2, reads "To realms"; but in the 1875 edition the original reading " To mansions" is restored.
In 1871, Mrs. Toke slightly altered the text for the Rev. R. Judd's Sunday School Liturgy & Hymn Book, No. 62 (Halifax), and wrote at the same time the following additional verse, which is given in Judd's collection as the first:—
"Thou hast gone up on high!
Triumphant o'er the grave,
And captive led captivity,
Thy ransomed ones to save.
Thou hast gone up on high!
Oh! help us to ascend,
And there with Thee continually,
In heart and spirit blend."
This stanza is practically unknown to compilers, and is not in general use.
