Since this is from before the “reforms” I gather it is a pagan ritual site?
My thought too. I don't recall any horse figurines or "Bart Simpson" looking characters being used in the building or furnishing of the Temple. The Old Testament is very specific about the furnishing of the Temple, pagans, on the other hand could have used just about anything in their idolatrous worship-----even Bart Simpson.
Yes, they are pagan, obviously, because idols are not used in the proper worship of God. Probably familial idols, often used to honor ancestors by people of those times. There is a scene in the movie “Gladiator” which depicts Russell Crowe’s character engaging in that type of observance, with similar small clay idols.
