Most mid-nineteenth-century members of The Church of Jesus Christ of Latter-day Saints in Wales were unable to read the Millennial Star because they did not read English. In July 1846 Captain Dan Jones began publishing Prophwyd y Jubili, or Prophet of the Jubilee, a periodical in the Welsh language that had a readership initially of six hundred Latter-day Saints. The final number of Prophet of the Jubilee, printed in December 1848, announced that the periodical would continue to appear monthly but would be called Udgorn Seion, or Zion's Trumpet. Readership by this time had increased to nearly four thousand. John S. Davis, a young man from the town of Carmarthen, was selected to be the editor and publisher of Zion's Trumpet. Through its pages, Davis defended the Church's doctrine, reported on missionary progress throughout Wales, gave instructions to Church members, and entertained his readers with poetry, proverbs, and humor. He also published Welsh translations of the Latter-day Saint standard works, together with two hymnals and a variety of pamphlets. Translated and edited by Ronald D. Dennis, professor of Welsh at Brigham Young University, the current volume is a facsimile edition of the twelve issues of Zioti's Trumpet that appeared during 1849. The physical appearance of the Welsh original has been reproduced with similar type fonts that have been slightly enlarged for this English translation.
