My friend Kathlyn Rath sent me this picture after the other blogs about horns.  This is from a church in Norway where her mothers grandparents were baptized.  Here is another picture and I like the clothes Moses is wearing in this one.

So I am not so sure how much of this is a metaphor.  There is a translation in the Vulgate, the Latin translation of the Old Testament, that says that when Moses came down the Mountain his face was “horned”.  This is an interesting and probably useless discussion but there are some folks that believe it is important because of the connection of God’s Holiness some of which Moses was alowed to see, and the horns on the altar in the tabernacle.
