Also see "Early Christian and Jewish Rituals Related to Temple Practices" by John A. Tvedtnes, available at FAIRLDS.org. This offers strong evidence for the ancient nature of the Temple. For related background information, see Mormonism and Early Christianity, the excellent Website by Barry Bickmore.
Just for fun, read the Coronation Ceremony for Queen Elizabeth II to learn about details of the Queen's coronation, based on ancient English traditions, which include anointing the queen with oil in several places, offering some interesting parallels to the Temple. It's one of many examples of ancient Temple-related practices that have diffused into other systems. (Thanks to Wade Englund for pointing out this page.)
