What is the different between coffins and caskets?

Both coffins and caskets are used for transporting the deceased, viewing, and burial, but the biggest difference is the shape. The top one is a coffin, having six sides and tapering at the head and feet. The lids are often separate and not hinged. The one on the floor is a casket, our more modern version with only four side and a hinged lid. The shape changed during the Civil War because the coffin was seen as more "morbid" while the new design was sleek, neat, and more Godly. Both can be wood or metal, and coffins are still available for modern burials, just not as common.
