The Christian hullaballoo concerning the Ten Commandments and the U.S. comes mainly from the very few references to Moses and the tablets that appear on the Supreme Court building (and a few other state courthouses). Deceptively, Christians will trot out the image of Moses without the context from which the statue sits. By using this subterfuge technique, political Christians want you to believe that, somehow, Moses and the tablets on the Supreme Court building represents proof that U.S. laws derived from the Ten Commandments. Nothing could stand further from the truth.
In the first place, Moses does not sit alone on the Supreme Court Frieze. Christians don't want you to know that Moses sits next to two Pagans-- Confucius and Solon:
This sculptural frieze appears on the back of the Supreme Court Building (the east side), not the main entrance, where you would expect him to appear if the sculptor intended him to hold a special place.
Moses sits next to Confucius and Solon holding two blank tablets. These fellows represent three lawgivers from the East, thus they appear on the east side of the building. Characters from the fable of the Tortoise and the Hare also appear on this frieze (go figure).
Moreover, Christians don't tell you that figures of 17 other lawgivers appear on the Supreme Court building. Notorious pagans such as Hammurabi, Menes, Lycurgus, Draco, Augustus, and Justinian also appear among the lawgivers. Even Mohammed holding the Koran appears on the building! (Can you imagine the uproar that would occur if U.S. Muslims declared that Constitutional law derived from Allah and the Holy Koran?) Friezes appear on all four sides of the building and on the inside. The Moses statue appears no larger than any of the other lawgivers. According to the Curator's office, Weinman designed for the Courtroom friezes, a procession of "great lawgivers of history," from many civilizations, to portray the development of secular law.
