Ben E. Roberts, the son of B. H. Roberts, acknowledges the existence of "A Parallel" in a letter to Mormon attorney and author Ariel L. Crowley. "A Parallel," which was originally eighteen typed pages, presents similarities between Ethan Smith's VIEW OF THE HEBREWS and the Book of Mormon and is arranged in parallel columns. It was presented to Apostle Richard R. Lyman in 1927 and had circulated in the Mormon underground. Copies of the document are passed out in 1946 at the Timpanogos Club of Salt Lake City on in 1946. It is subsequently published in the Rocky Mountain Mason in 1956. VIEW OF THE HEBREWS was published in New York shortly before the Book of Mormon.
