The exact meaning of the name Soria Moria is not known. It may be related to Moriah, the name given to a mountain range in the Book of Genesis. According to tradition, this was the place where Abraham almost sacrificed Isaac. JRR Tolkien acknowledged that the name (in sound, not meaning) lay behind his Mines of Moria. It could also be related to the Greek words sophia and moria which mean wisdom and foolishness.
