The Horns of Moses are an iconographic convention common in Latin Christianity whereby Moses was presented as having two horns on his head, later replaced by rays of light. The idea comes from a translation, or mis-translation, of a Hebrew term in Jerome's Latin Vulgate Bible, and many later vernacular translations dependent on that. Moses is said to be "horned", or radiant, or glorified, after he sees God who presents him with the tablets of the law in the Book of Exodus.
The use of the term "horned" to describe Moses in fact predates Jerome, and can be traced to the Greek Jewish scholar Aquila of Sinope (fl. 130), whose Greek translations were well known to Jerome. The Hebrew qāran may reflect an allegorical concept of "glorified", or rings of light. Horns tend to have positive associations in the Old Testament, and in ancient Middle Eastern culture more widely, but are associated with negative forces in the Book of Revelation in the New Testament. These considerations may have influenced the translators in their choices, for Aquila as a positive, or for Jerome, as a negative.
