1846, January 4. Since the death of Joseph and Hyrum, the building of the [Nauvoo] temple has gone on rapidly and contrary to the expectation and prophecy of Sidney Rigdon and others. The roof has been put on, the spire put up and beautifully ornamented. The temple is indeed a noble structure, and I suppose the architects of our day know not of what order to call it, Gothic, Doric, Corinthian or what. I call it heavenly. The upper room is finished and about the beginning of December it was dedicated and the Twelve began to give to the Saints their endowment.
