The Salt Lake Temple Angel Moroni Statue
The Salt Lake Temple was the first temple that featured a golden statue of the Angel Moroni. The original Nauvoo temple had a flying angel weather vane. Moroni was the angelic messenger from God that showed Joseph Smith the location of the golden plates; which the prophet would translate into The Book of Mormon. Moroni was also the angel that showed the golden plates to the Three Witnesses.
The Moroni statue was designed by sculptor Cyrus Dallin, who was not a Mormon. He drew his inspiration from Revelation 14:6, "And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people."
His design of Moroni blowing his trumpet symbolizes the angel proclaiming the Gospel of Jesus Christ to the world and calling people to repentance.
The statue depicts Moroni wearing a robe. The robe symbolizes righteousness. (Isaiah 61:10)
The statue also depicts Moroni wearing a crown on his head, not a halo. The crown symbolizes glory and exaltation in God's kingdom. (1 Peter 5:4)
The statue faces East, symbolically looking for the return of Christ who will be coming from the East at His Second Coming. (Matthew 24:27)
Here's some trivia. The capstone Moroni is standing on is hollow. It contains sheet music for hymns composed specifically for the temple dedication; a polished brass plate that contains the name of the temple architect and all the church general authorities at the time of dedication; the Bible, Book of Mormon, Doctrine and Covenants, and Pearl of Great Price. It also contains the books, "Voice of Warning", "Spencer's Letters", "Key to Theology", a hymn book, a compendium, and pictures or photographs of Joseph Smith, Hyrum Smith, Brigham Young, John Taylor, Wilford Woodruff, George Q. Cannon, and Joseph F. Smith and a photograph of the Salt Lake Temple as it was the day of dedication.
The Moroni statue on the Salt Lake Temple is made of solid bronze and it weighs about three tons. A counterbalance is attached to the statue’s feet and is anchored inside the temple spire where Moroni is standing. This holds the statue in place, but also allows the statue to move slightly in the wind without breaking.
