Claymation is a relatively early form of animation

I think it may be Stop Motion. Stop motion is a fairly early form of animation. You take a photo, then move the object/sculpture to a different position etc. Then take continuous photos with the sculpture/object in a different environment or position. It's very time consuming though.
Hope this helps!

What i think is that it adds loudness for preachers/church choirs. it is also able to hold up a lot of weight without pillars. : )) idek tho
