On Wednesday, August 16, 1967, in a missionary apartment in Regensburg, Germany, John W. Welch identified the ancient poetic form chiasmus in the Book of Mormon, and LDS scriptural scholarship changed forever. You are invited to join us on Wednesday, August 16, 2017, at 7 pm in the Joseph Smith Building Auditorium on BYU campus to celebrate the fiftieth anniversary of this remarkable discovery and the scholarly flowering that ensued. Join BYU President Kevin J. Worthen, Dr. Welch, and other guests for an unforgettable evening of music, art, entertainment and inspiration. An academic conference open to the public titled "Writers, Readers, and Chiasmus" will bring visiting scholars to the Harold B. Lee Library Theater beginning at 9 am on Tuesday, August 15, and Wednesday, August 16, 2017. This event is sponsored by the Harold B. Lee Library, BYU Studies, Book of Mormon Central, Interpreter Foundation, and the John A. Widtsoe Foundation. A video of the events will be posted at Book of Mormon Central and on our website at a later date.
